umadbro

A phrase previously used by trolls, but now used by 12 year old's trying to be cool.

Was used on the image board 4chan.

But now spread around Youtube and Runescape by fucking conformists. Thus making this phrase the most annoying piece of shit ever to come onto the internets.

Seriously, it's even worse than 'coolstorybro'
Jim: You're an ass hole

12y.oconformist: "umadbro"

Mature people: Fucking egg in a bun.
