The feminine heteronormative equivalent of 'no homo'.
A colloquial expression, often used by chicks after “inadvertently” alluding to or engaging in a decidedly lesbian act. Use of this phrase automatically negates any lesbian ambiguity generated by said act, and thus, it is perfectly acceptable for two teenage chicks, OR a couple of middle-aged conservative mothers to scissor each other all night long, as long as ‘no lesbo’ is said soon thereafter.
Teenage Girl #1: That chick over there has a nice rack.
Teenage Girl #2: Yeah, I'd like to munch on her rug all night long.
*Both girls look at each suspiciously*
Teenage Girl #1: No lesbo, though, right?
Teenage Girl #2: Yeah, no lesbo.
Phrase used after one inadvertently says something that sounds lesbian. See no homo.
Her ass is mine, no lesbo.
