look up any word, like sex:
 
1.
"Innage" is the term for when a male is receiving signs of sexual interest from a female.

Derived from the idea of being/getting "in" with a girl - which means to be her sexual interest, and most likely on track for a boyfriend position or casual sex.
Anthony = Dude, that chick straight up just asked me out!

Mike = OMG MAJOR INNAGE BRO! GO FOR IT
