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.

Similar to a shart, a sloop is the action of accidentally defecating in your sleep. This generally results in a sticky poo mess in the morning.
Remember that time slanty-eyed Paul slooped? He woke up in the middle of the night covered in his own excrement. Good times.

The disgusting sound that you make with your mouth when you're eating anything from the raw bar at a seafood restaurant, especially clams and oysters. A combination of a vacuuming, slurping, and crunching sound.
To really get at all the meat in an oyster, you have to give it a good sloop.
