the worst rock band to ever score a #1 hit. Screechy singing, sloppy and derivative guitar playing, cock rock lyrics, shitty songs, cliches - everything about them just plain sucks.

When you meet a MrBig, they usually come off as a traditional gamer dude but then as you get to know them you can find out how fun and chill they can be.

Many MrBig's are very friendly and smart but aren't afraid to absolutely thrash you in any video game. They are kind, have a very good sense of humour, love to laugh and have a very strange taste in music. MrBig's are extremely hardworking and never stop trying to achieve their dreams.

But be warned, even though MrBig's seem to be very innocent, they won't hesitate to write smut about you and your uncle just to disturb you......and they'll enjoy it
