Fap humping, it was made up in palringo's "official PIMD" group long before people disgraced it with things such as farting on dicks.

Fap humping is you fapping as you hump someone.

To give affection to your pet or another person with your foot.
Usually when you are too lazy to reach down and pet your kitty, you'll fump her instead, using your feet to stroke her fur.

Combination of 'fart' and 'dump.' A fump is when you think you have to take a big shit, but when you sit on the toilet to do it, you just let out a huge, explosive fart. Some small, misshapen pieces of poo usually accompany a fump.
"Man I thought I had to take a huge shit, but it was just a fump."
