When you take your hand and make it into a
beak shape by clenching your fingers
together. Then use it to
pleasure your own or a friend anally
“I met this hot
girl, can’t wait to suprise her with a Buttbeak”
Friend - “what are you up to tonight?”
Friend 2 - “Not much, might hit the town and do some buttbeaking”
(Sung with a best) “If you want to Buttbeak
like a Pro, use plenty of
Lube and take it nice and slow”
