An exclamation used to inform one's friends and acquaintances about a successful hook-up. Only applies to sexual intercourse, although fewer points may be allotted for scoring a base run if the player doesn't make it all the way home. Especially useful if you don't want everyone in the room to know about your sexual escapades.
Person 1: Hey man, where were you last night? We waited for an hour before we left!

Person 1: Oh, we're cool then

Orgasmic exclamation uttered when fucking a guy who looks like the spitting image of The Boy Who Lived. Either you're role playing, or it just comes out involuntarily when he shoots his gunk inside you. Used by straight gals as well as gay guys who love the kink of bottoming for a Potter lookalike.
"Damn, I'm so close... ooo ahhh uhhhhHHHH!"
"Oh baby... 50 points for Gryffindor!"

a phrase used to communicate that you just had sex
I finally had sex with my last girlfriend. After we finally did it for the first time, I reached across her, grabbed my cell, and text my friend "10 points for Gryffindor!"

The term defining the event where a man and a woman are having intercourse in a bedroom, and upon the time of finishing, a third party who has been hiding in the closet, unbeknowsnt to the man or woman, jumps out and yells "TEN POINTS FOR GRYFFINDOR!!!" and promptly runs out of the room. Usually works best with random hook ups, but also is well suited for sex within a relationship.
"Yo dude, you remember how Chris was with that random girl last night? I so ten points for gryffindored them"

Gryffindor is one of the four Houses of Hogwarts School of Witchcraft and Wizardry, founded by Godric Gryffindor. Godric instructed the sorting hat to choose a few particular characteristics he most values. Such character traits of students Sorted into Gryffindor are courage, chivalry, and determination. The emblematic animal is a lion, and its colours are red and gold.1 Sir Nicholas de Mimsy-Porpington, also known as "Nearly Headless Nick" is the house ghost.

Gryffindor corresponds roughly to the element of fire, and it is for that reason that the colours red and gold were chosen to represent the House1.The colour of fire corresponds to that of a lion as well, red representing the mane and tail and gold representing the coat.
Harry Potter used to belong to the House of Gryffindor during his time at the Hogwarts School of Witchcraft and Wizardry.
