Homostasis

Not to be mistaken with homeostasis (n.)

The delicate domain of equilibrium within a heterosexual person that prevents them from being too insecurely homophobic and being too obnoxiously gay in social situations.

i.e. Right between acting too straight and too gay

Todd and I had to share a tiny couch at a friend's place the other night but it's alright - I said "no homo" so I didn't break homostasis.
