Wet Slug
A wet, ejaculate covered flaccid penis, post sexual intercourse.
Roger's girlfriend continued to pull on his wet slug but he was spent and couldn't get it hard again.
Wet Slug
When you masterbate just enough to make it drip a little. Then chill out for a few so it's all slimy and limp. Then you trail it, ever so gently, across the exposed skin of an unsuspecting victim. This leaves them with a gooey trail leading to a nice warm slug. Oh yeah, the more public, the better.
The party was lame until the slut in the miniskirt found my wet slug on her thigh.
