PUTTING HIS HANDS UP!
CLUE #1: In 2011, He wrote "Hands Up" for 2PM.
You can see the video here.
CLUE #2: Look for JYP's hands in the video above.
CLUE #3: He tried to Put (Got7's) Hands Up
CLUE #4: Sneaking this dance move into Got7's "If You Do" Choreography.
If you didn't know, JYP made up the dance moves for their title track. (source: here). I guess, since the song he wrote didn't make it as title track, he needs to "raise his hands" somewhere else.
Notice: Yugyeom was probably frustrated with putting his hands up. LOL.
