Grimin it up 

The process of shiting on the floor in the middle of a mosh pit. The ensuing chaos that follows results in the floor being covered in a thick layer of excrement, therefore, griming it up

After peer pressuring our friend Ben to no end, he jumped into the crowd and started Grimin it up. A few short minutes later he was escorted out by authorities

Ad Graminum

An attack on an opponent's grammar to completely discredit his/her argument.

See Ad hominem.

Faiz: I spent a good half-hour typing out an argument for nothing, because someone used Ad Graminum and pointed out my "your" that should have been "you're".

Julian: You deserved that.

Brian: The Lakers are fundamentally a much better team, they're offense is-
Julian: HA! "THEIR"!
Brian: Fuck you.

Grimith

Grimith is a not-that-well-known gaming commentator on the website Youtube, as well as on the VoltronArmy forums. He is well known within the VoltronArmy community, but on Youtube and elsewhere, much less so. Views of Grimith differ, as some find his vulgar language, as well as his maniacal behavior concerning. Others, however, see Grimith as one of the pinnacles in the game commentating community of Youtube, however little-known he is. He is liked by most for playing lesser-known games, his sense of humor, and his sometimes hilariously morbid behavior.

Some of his most liked series of gaming are the "Trilby Quadrilogy," King of Dragon Pass, Sid Meier's games, Romance of the Three Kingdoms games, Star Zoo, Daggerfall , Liberal Crime Squad ,and Nintendo games.

He is considered by many to be a great man, however loosely the term is applied.

Liberal Comrade: "Did you see that new video Grimith uploaded?"

Moderate Potential: "Yeah it was pretty good; made me laugh."

Conservative Scum: "Horrible. Absolutely horrible. Never shall I be free of the sights and sounds i have experienced on this day!"
