Celebrities are known trendsetters. They start a fad, influence opinions and tastes, turn a craze into mania. Everyone gets on their bus.

But in this age of social media, they don't just dictate the uso. They sometimes become the uso and even nakikiuso.

Year 2015 in the local scene saw the rise of bold fashion statements and all sorts of #goals as well as the revival of some classics, including those that were once baduy.

It was also ablaze with bombshells and phenomena.

There were words and phrases that became favorite expressions and spoofy videos that bred Internet sensations and superstars.

PEP.ph (Philippine Entertainment Portal) rounds up 15 of these trends that became patok na patok in showbiz.

15. Round shades

Yup, anything but square frames were all the rage last year because they instantly added playfulness to any look.

14. Biker guys

Whether traffic made them do it, as Jericho Rosales had done, or simply an adrenaline rush, as Sam Milby put it, more male celebs were riding the motorcycles last year.

13. Prints, stripes, and checkered togs galore!

What used to be a no-no in stylish dressing became "a bold statement, fashion-forward, defying convention" in 2015.

Vice Ganda, Coleen Garcia, Kim Jones and Whong Navarro were among the celebs who went around in floral printed and striped ensembles, and they pulled it off, fashionably so.

And prints on shoes and bags had become so cool.

12. Achieve!

There was something about the way James Reid delivered it as Clark in his television series with Nadine Lustre, On The Wings Of Love.

He effortlessly "achieved" being so cool and charming and cute.

Hence, the word became a favorite expression, along with "Push," "Ikaw na," and "Juskolord."

11. #WalangForever

The phrase actually became a popular "hugot" in 2014.

Its impact, however, was felt this year because of Dan Villegas's film, starring Jennylyn Mercado and Jericho Rosales. Walang Forever was hailed Best Picture in the recently concluded Metro Manila Film Festival 2015.

COMELEC also used it as a catchphrase during the last day of voter registration.

@Walkah_Walkahon Twitter

Even Vice President Jejomar Binay's camp used it on Twitter in retort to the statement of Edwin Lacierda, presidential spokesperson of President Benigno S. Aquino III.

Ironically, though, it was popularized by Vice Ganda whose Beauty and the Bestie was also an MMFF entry.

Remember his line, "Walang forever sa taong bitter?"

10. NaeNae Dance

Kamilya stars caught the NaeNae fever when ASAP 2015 went to London last October.

Julia Barretto summed up their fun on Instagram:

#WeAreDoingTheNaeNaeEverywhere

Angelica Yap related her love woes in a very creative and viral way by making a parallel between coping with a heartbreak and the making of a pastillas.

Her video caught the attention of It's Showtime!, resulting in a segment dedicated to the search for her Mr. Pastillas.

She was pitted against Eat Bulaga!'s Yaya Dub.

6. (Tie) Maria Sofia Love's Pak! Pak! Pak! Tuloy ang laban, mowdeling...

After the video of this London-based transwoman went viral last July, one of the first celebs to impersonate her was Heart Evangelista.

The year's most gasgas hashtag was about #goals.

From #SquadGoals, which basically means a thing or things that a group of friends must have...

Internet now has #RelationshipGoals, #TravelGoals, #FitnessGoals, #BodyGoals, #FriendshipGoals, and #AllGoals.

Everything was really a #Goal thing...

4. Pabebe Girls

Some stars went baliw na baliw with the Pabebe Warriors video of pre-teens Janet Ricabo and Michelle Alfonso.

Among the celebs who spoofed their video were Kim Chiu and Alex Gonzaga, Solenn Heussaff and Iya Villania, Yaya Dub and Lola Nidora.

3. Pabebe Wave

This hand gesture that launched thousands of selfies and videos was a pauso of Yaya Dub.

When Eat Bulaga! declared September 26 as the National Pabebe Wave Day, it was participated by Kapuso and Kapamilya alike, politicians, sportsmen, Hollywood singers and celebrities, and people from different walks of life.

It had also caught the attention of foreign media, including BBC.

1. AlDub

Undoubtedly, the tandem of Yaya Dub and Alden Richards was 2015's biggest trend.

Their accomplishments in a span of five months remain unprecedented.

They broke trending records on Twitter and ratings on television.

They achieved remarkable numbers on social media and endorsement brands.

They conquered various platforms: Internet, TV, concert stage, and, recently, the movies.

They have shaken showbiz and taken it by storm. Celebs watch them and wanna have a selfie with them.

Kung hindi mo gusto ang AlDub, lagot ka.

And anything associated with them had become a craze and a conversation piece??from Bryan White's "God Gave Me You" and their kalyeserye playlist to Yaya Dub's polka-dot apron to the plywood that separated them during the first meeting to the long table that Lola Nidora made them use on their first date to their Philippine Arena show to AlDubYou to AlDub nation, which has a formidable online presence.

Naysayers are declaring their popularity has started dwindling.

Maybe so, but what Yaya Dub and Alden have accomplished in such a short time will remain a tough act to follow in the near and far future.
