The person that asks a girl to be his girlfriend and when she says no, the next day he asks the girls best friend to be is girlfriend because he is a cheater and an ash hole.
Girl: Grant is an ash hole.
Girls friend: Oh I am his girlfriend sooo...
The most annoying, rude, shrimp dick boys out there. They have awful personalities and are hella ugly. They also think being aggressive is a personality trait
Man 1: "Grant is such a faggot. I mean, why does anybody hang out with that failed abortion?
Man 2: "I know right, I hope one day that piece of shit gets raped by a pack of vultures."
Man 1: "I hope one day, that human garbage can contracts aids from all the monkeys and animals he's fucked."
Man 2: "Grant is definitively the human representation of a piece of shit."
The eternal douchebag. A mentally deficient person, or someone who acts in a self-defeating or significantly counterproductive way. Archaically the word mome has also been used. The similar terms moron, imbecile, and cretin have all gained specialized meanings in modern times.
A complete and utter wanker who sports a very bad fringe/haircut. A Grant is often seen mistreating people despite the fact that he really has no room to be choosy regarding friends (namely due to his bad haircut)
Shit, man, I'll go and shave it all off right this second; I'd rather look like a giantthumb than a Grant :(!
