The act of slightly leaning against a friend of the female persuasion, which may be misconstrued as consensual same-sex-attraction-giving-vibes.
(Suitemate walks in on two friends leaning against eachother while watching a movie)

Suitemate: You two are totally lesbian leaning right now!

Or my favorite pseudo-homophobic moment:
(You find out your old friend just came out)
Self: Holey guac! (Fill in said Leaner's name) totally just came out! I hope we didn't accidentally lesbian lean!
