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.
I saw Mr. Big as an opening act for Rush in 1990 and boy did they ever ess you cee kay. They were so awful most of the people on the grounds got up and went underneath the bleachers until the 45 minute set was up. We all remarked about how extreme the band was in their flat-out suckability. They were the worst band I had ever seen in my life. Rush came on stage after that and rocked the house, like I knew they would. Mr. Big sucks out the ass. Big time.

Someone that thinks he's the Alpha male of the group when he's actually an equal or just the group's bitch.

Typically wears vest tops, revealing the lack of muscle on his arms. He's also loud and pretentious to compensate for his tiny cheese puff penis.

If you happen to notice one of your fellow group members turning into a Mr Big Time you should:
1. Confer with other group members to confirm the transformation
2. Stop calling him by name and instead, in a high pitched piss take voice, call him 'Big Time'

This will ensure he is reminded of where he stands within the group, not as a leader but as an equal or possibly less than, depending on the severity of the situation.
Mr Big Time (pretentious friend): *Puts on vest top and acts as if muscular*

Group: 'ooooo Big Time'

1. A title given to a guy who's attitude exudes self confidence, an alpha male type presence, or an "I'm better than you but I don't feel the need to point it out" type aura.

This type of behavior is most common in short males when they are around their significant other.
Male 1: hey dude look at Matt over there.
Male 2: What do you mean?
Male 1: He's sitting over there like Mr. Big Dick with his arm over his girlfriend like that.
Male 2: Oh yea, but you know he's short and short guys need to like assert their dominance and whatnot...
