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.

Phrase used after one inadvertently says something that sounds lesbian. See no homo.
