“Uh, I dont mean to sound ignorant, but just what is the LGBTQ community? Bacon, lettuce and tomato loving Quaalude gobblers?”
Some of it is: Lesbian,Gay,Bisexual,Transsexual (I am not sure of the Q, but someone else certainly knows.)
Another poster mentioned it. Q is for Questioning.
I prefer the sarcastic term "questionable".
Cheers!
