look up any word, like dirty sanchez:
 
1.
The last few drops of urine that end up in your underwear, pants, or running down your leg, usually from under-shaking.

Especially awkward in shorts, when the fluid can run visibly down your leg.

If left untreated for extended periods of time, it can often create an uncomfortable odor, that repels other people, but often attracts insects.
Example #1: Harold was in a hurry, so when he shook and pulled up his pants, he was not surprised about his dose of After Funk.

Example #2: "Ahhh, dude I just got like a tablespoon of After Funk!"
