Summing

When one Sings and Humms at the same time! It is quite a pleasant sound a bit like a young walrus' mating call!

*SUMS*

Acronym for "Super Ultra Mega Slap"

Used when insulting or scolding someone for what one thinks is tasteless, immoral, or just fucking retarded.

May also be followed by an actual slap.

Coined in 2004, by a kid with an itchy fro and another kid who was just trying to fit in.

Me - Hey Colton, I just went out and bought the new Nightmare Creatures game!

sum

A game where when someone says something stupid and you get to hit them on the head for it. After someone says the stupid statement, you immediately say "That's sum." while rubbing your fingers in the air like the sign for paying money.

Mick, "I drank 7 out of the last 5 days"
Al & Calvin, "That's sum, asshole (rubbing fingers in the air)."
then Al & Calvin each get to slap mick on the top of the head.
