Lol SKREEE

an "Lol SKREEEE" is what one shouts when they do something rude but funny. Kinda like saying "PRANK'D!" but more Jack-ish.

Example:

"Billy: Jessamine you so ugly lol.

Jessamine: Uh, excuse me?!

Billy: Lol SKREEEE jk lassie"

Skree
Skree, when not accompanied by an "Lol", is used as a victory screech of sorts. Ex:

Billy: *punches Will*

Will: "ow u win"

Billy: "SKREEEEEEE"
