1. To be "cock-blocked" by a lesbian. 2. When a lesbian steals your girlfriend.
I was hitting it off with this hot girl at the club last night, until a total act of lesbianoge left me all alone.
the act of attempting to turn a straight girl into a lesbian by interfering in daily activities including but not limited to being the third wheel on dates, talking badly about any boys she shows an interest in, trying to change her appearance by talking her into a butch haircut and flannel shirts, etc....
Woah! Get a load of the lesbianoge going on over there! (said while watching a straight girl who is on a date with her boyfriend and the lesbian who tagged along is trying to control the conversation.)
