Tribbling is when one passes gas and it makes a purring sound as it leaves the anus, similar to the trill of the creatures from the Star Trek episode, "The Trouble With Tribbles".
OH my god, I was just tribbling. I just farted and it sounded like a Star Trek tribble. I don't why that made me think of you, but it did.
A man who is insecure, untrustworthy, lies, cheats, manipulates, a snake, who will pay for sex, has no standards, sleeps with anyone, is community dick, lacks motivation, has nothing to offer but misery, and when he does wrong doesn't care who he hurts, and never apologizes.
