A Canadian spider who from time to time will jump off the ground and fly a short distance, landing on someone's face. It will then begin to munch and chew on the unfortunate person's face.
Some cooking show: "The rare Canadian facemuncher can sometimes be found in herbal teas and other such drinks."
vt. - To completely dominate and/or thoroughly eviscerate someone in some means of competition, usually video games. See also pwn.
n. - One who is on the receiving end of a consequent facehump. To be completely embarrassed from the actions taken in some means of competition, that some have to wonder if there is a severe mental deficiency or a considerable physical limitation that caused the facehumpage in the first place.
Because, you just don't facehump retarded people or the elderly. It would be fuckin' funny, but sooooo wrong...
Background: Imagine someone making a humping motion with their groin. Insert face at hump. There ya go.
"Man, you just got FACEHUMPED!"
"No, I didn't!"
"Dude, look at the score. 16-1. Total facehumpage."
"Yeah, well, I did your mom last night! And, I really DID facehump her! OWNED!"
"...Dude, my mom died last night. From suffocation."
"R-really? I'm sorry, bro..."
"HAH! Just kidding! Yet again, FACEHUMPED!"
"Dude, you're an ass."
The act of conducting routine Facebook activities while perched on the throne taking a dump, commonly on a mobile device, usually at one's place of work. See also, toiletbooking, duecebooking, and multi-tasking.
I like to do a little Facedumping while I "drop the kids off at the pool" every morning at work. It helps me relax.
Did you notice he always has his iphone with him when he goes into the can, man, you know he's totally Facedumping in there.
v. The act of leaving ones facebook alone and unattended around drunk, creative young adults with nothing better to do than fuck with each other. The consequences can be devastating. Changed names, relationship statuses and your grandmas photos fro her trip to the bahamas are all free game. One can only untag, apologize, explain to your aunt why you "liked" anal sex and move on. Turn facebook into fun with Facemucked.
