look up any word, like eiffel tower:
 
1.
epal sa usapang lasing; laging nangongontra nakaka bad vibes; possibleng nasasapak lagi sa inuman or pinapauwi nalang.

(A person who always interrupts drunken conversations; someone who always contradicts people and causes bad vibes; person who possibly always gets socked in drinking sessions and gets asked to go home instead of getting their ass kicked)
I sometimes am guilty of being a contradictor.

someone who says they are a red sox fan but really they are a yankee fan
look at that contradictor over there in the stands
