Broster

A Broster is a bro that tries to be a hipster. Generally they have their pants turned up once, or shorts just above the knee. Not too high. They wear hawaiian shirts and bright neon hats. They call themselves hipsters as well. Typically they are in frats. Brosters are not to be confused with hipsters.

Guy 1: That dude is a total hipster!
Guy 2: Nah man, He's fakin. Definitely a bro turned broster.
Guy 1: wow lame

My biological brother, who is now transgender completed, is my broster. He used to be my brother (bro), but now he’s my si(ster); hence, broster. We need more words to describe these relationship changes.

My broster invited me to her home for dinner.

Broster

Combination of Brother and Sister

A brother who acts girly, or sister who's one of the lads !
Could be used for friends, with platonic friendship.

Broster : '' Like a sibling, but even better.''

Broster

1) Short form word describing one's sister-in-law's brother, as it is ordinarily too long and complicated to explain the relation - as the individual is not really family, but is more than a random friend

1) I'm heading out on the town tonight with my broster

Broster

IN some parts of South-East England, the word 'Broster' is used to describe something that has gone seriously wrong. The term was derived from one AS chemistry student who relentlessly dropped glassware by accident throughout the year. As the term became more widely used, to 'Broster something up' or 'brostered' became used for anything that has gone badly wrong, so it was no longer only applicable to broken glassware.

broster

A combination of a bro and a hipster. Has the party-lovin attitude of a bro but the pretentious taste of a hipster.

Broster: Dude, you wanna chill and drink some 40s after the Akron show?
