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.

Fap humping is you fapping as you hump someone.

All of the past definitions are false. There is only one true definition for "Fump" It is a word made up by a child a few months ago and it's defenition is a goblin-like creature with a large head and green skin. The word fump can be used as a verb (to fump) a noun (a fump) an adverb (fumpily) and a adjective (fumpy).
Dude, I just saw a fump!
Dude, I swear he fumped right on the fump!
You fumped SO fumpily.
Well, you're quite fumpy.

Deborah has to sit both away from her desk and leaning forward out of her chair because her fump won't allow her to sit otherwise.
