Small patch of hair just below the lower lip. It's called a bum tickler because it tickles a chicks bum when performing cunnilingus.
Ah man, he's got shit in his bum tickler!
A large erected penis. A male or female rubs it on the anus and it sends a shock through the rectum. This experience is worth while
"Ooo John, give me a bumtickler, I'm horny!"
Abnormally long toe hairs. So long in fact that when placed on someones backside they tickle.
My Boyfriends Bumticklers keep me up all night.
Hey man, I wish I could meet more chicks but I've got these damn Bumticklers.....
