What is Bottle Cap?
1.
when recieving a hand job, right before you climax the girl (or guy if you want) smacks the head of the penis, as if trying to put a cap on a bottle
she didnt know how to give a hand job, so i told her it was like trying to get ketchup out of a bottle, so she was going up and down and right before i came, she gave me a bottle cap,and it still hurts

A shallow, uninteresting person.
I can't carry on a conversation with her for more than 5 minutes, because she's such a bottle cap.
