Dude 1: Oh man dude I only sloop for 3 hours last night.
Dude 2: Were you too busy watching YouTube?
Dude 1: Yeah.
Dude 2: Heh LOL!

A word used by kaypeacreations by accident during an exhaustion fueled video to explain the action of sloping the sculpted fur on the face of a clay art doll.
If you look at your reference you can see that the fur kind of sloops in different directions depending on where it is on the face.

Sloop is a more quirkier manner of suggesting one is in an excessive need of sleep but is present in a gathering of friends, and so, painfully refrains oneself from passing out at any given moment because of the lack of sleep, and proceeds to joke around, telling people he/she needs to “sloop” laughs, and ones friends join him/her with laughter, but we all know that one never sleeps, therefore sloops.
“Dude, I want to sloop. Hahaha just kidding, you guys are my only friends, I’m not gonna go sleep and miss this sweet sweet socialising. I could die of sleep deprivation, nah, just kidding AGAIN”

Saying sloop is when you signal to others you will sleep but after 24:00/00:00.
"Sorry guy's I got to sloop."

An indescribably rancid, thin sludge like material. Smells foul and is found in certain locations such as: Under the fridge, in the drain, in tubby kid's 'pits, and 7 day old coffee.

Do not eat the sloop.
Eugh, I found some sloop in my locker. I'm gonna order some HAZMAT people or something.
