Wikicracker 

Someone who categorically disputes the accuracy of Wikipedia without knowledge of specific examples. This person believes that Wikipedia is not a 'real encyclopedia' because it doesn't follow a traditional writing / editing process.

Even though Mike was an expert in barebacking, he was just plaing the roll of wikicracker by disputing the Wiki entry, since he didn't even bother reading what was written.

A smart or facetious remark

James: You look pretty, Priscilla.

Priscilla: Thank you!

James: Pretty damn ugly! (Laughs)

A classic James wisecrack. James is a wisecracker.

Bud Wisecracker

A dude who starts slinging insults after he's had a few brews (such as budweiser).

BUD WISECRACKER: Hey, Pamela, you got some nice titties on ya! Come over here and let me suck on your nips!

PAMELA: Shut up, Asshole!

BUD WISECRACKER: What are you lookin' at Tommy.

SMASH!!! Tommy's fist knocks out all of Bud's front teeth and sends him on a snooze cruise.
