When you are having intercourse with a female with a very hairy pussy, while having a massive bush. Some point during the intercourse, the male will pull out and pee on the females hair and vice versa. When about to climax the male will pull out again and cum in the females bush.
So i met this chick the other day with a massive bush! So of course i did the derris and wetty to her.

Another word for to describe an occurance in life
"So when someone says wetty, you're in a room and someone says wetty, a vibe shifts... an organism shifts... and the feeling that someone has moves from there *gestures near* to there *gestures further away*, and you realise oh... oh that is wetty. If you didn't think it was in the past... if you didn't think it was wetty in the past and all of a sudden it hits you, you think actually, that is quite wetty
