1.
An aunt who is also a lesbian. If she has a wife/life partner, they are a pair of Lesbiaunts. Pronounced "Lez-bee-ahnt."
"My gay relatives are coming over."
"Your lesbiaunt or your guncle?"
"The whole crew!"

2.
Female relative who has jumped the fence.
Dude, my mom's sister dumped worthless Uncle Earl, hooked up w/that husky butch in the flannel shirt from the food Co-op, and moved to Vermont. Now, she's my lesbi-aunt
