When you have sex with someone and they make a high pitched noise like "AYEEEE" or "OOOOOO" As if they are in a choir concert singing a song.
Dude 1: I was getting head so last night and i was singing fall setta!!
Girl 1: His dick was so big it had me saying "AAAAHH" OHHHHH" I was saying fall setta
Dude 2: Man last night I fucked a girl and she was crying fall setta.
