look up any word, like sex:
 
1.
Youngjae is the lead vocalist in the Korean Boyband, B.A.P. discovered to be a fucking asshat in their latest music video, One Shot.
MY NIGGA YONGGUK ROBS AN ARMORED CAR TO SAVE YOUNGJAE AND THIS NIG SET HIM UP WITH THE POLICE
BETRAYED, MOTHERFUCKER.

If you were to look up the word 'betrayer' in the dictionary, you'd find Youngjae's face.
