tattle ball

A curdled gob of semen that clings to pubic hair, similar to 'dingleberry'. These rubbery little nuggets are so-called because when discovered by a lover, they 'tattle' on the possessor for having had sex with someone else within recent memory.

Dude, I was eating my girl's pussy and her muff was full of tattle balls. She's been fucking somebody else!
