Big fraud who poops his pants

From Wiki Gonzalez

Sammy Sosa is a big fraud who poops his pants -- at least according to NTR Jay Mariotti (http://web.archive.org/web/20030618031613/www.baseballprimer.com/chatter/archives/00000597.shtml#97), in perhaps the funniest Primer parody post of all time.

The concept has been reused (run into the ground?) to deride an indignant baseball columnist, or an actual big fraud who poops his pants. tina, the Colin Farrell fan, has used the term to deride actor Brad Pitt.
