Borsty
An insult to someone (usually a male) who thinks very highly of himself. Most likely, a Borsty makes music very similar to Justin Bieber with a vague twist of punk rock. A Borsty is highly spoiled and will usually gloat about his successions in music and almost everything else. In some cases, if angered enough, a Borsty will threaten Gingers and small Indie kids
That Borsty's new song really shows how highly he thinks of himself
