A phrase used by gay people when they want to compliment a woman on her looks, they may say "You turn me"- the woman looks so beautiful that she turns them from gay to straight.
*Amanda walks into the room*
Straight guy: You look beautiful tonight
Gay guy: Amanda you turn me
This term, "Hello, you're quite good at turning me on" originated back 200 years ago in the time of the olympians. This term can be used as a 'pickup- line' attempt, and usually results with a slap in the face. On rare occasions it may be worse, for example: you may be kicked in the genitals, but do not fear, the pain will go away quickly, due to the fact that you will be unconscious.
When you're walking down the street and you see a woman with a nice booty walking in front of you. You are now infatuated until she turns around and you see that she in fact, looks like a horse.
*walking around at school
Guy 1: dude that girl is hot
Guy 2: wait for it *girl turns around
Guy 1: DAMN SHE UGLY
Guy 2: that is a what I call a turn around make me frown.
