A competitive sport in a 3D sandbox indie game called Minecraft. Gameplay consists of removing floor blocks from a stadium to make other players fall through the floor. The last player standing is declared the winner. After the game the floor is filled back in and the players compete again. Spleef is played in a specialized "Spleef Arena" composed of the main Spleef floor, a viewing area, and a lower floor to catch losers. The name is a pun on the word Grief, as the players resemble Griefers trying to make the other players fall through a floor.
Oh man, that last round of Spleef was intense!

The act of letting air escape the corner of your mouth upon toking on a joint, resulting in an accidental raspberry. The name is derived from the term 'queef', a vaginal fart, and spliff, a coloquial term for the combination of tobacco and marijuana.

Sydney: Ha ha, Finn just Spleefed. What a Spleefhead

Ya. Me and some friends made this word up back in 1983 or 1984 in Brockton Massachusetts. A spleef is a marijuana joint. We also at the same time made up the word zabe, which was a term referring to a rolling paper. Making up terms and throwing them into the popular lexicon is like throwing shit against the wall, sometimes it sticks, sometimes not. Spleef stuck.

Two other terms we made up during this time referred to a woman's squishy spots. One was cum dumpster and the other was hog garage.
If we had a zabe we could roll a spleef.
