Coined at the turn of the 21st century (circa 2002), this term was commonly associated and later named after the infamous Ohio resident and socialite, Travis Lipscomb. Travis was attributed this colloquial term due to a flesh eating virus he contracted, causing a potent stench of feces to arise from his knee area, and into the unsuspecting nostrils of millions. Thus, the name was born.
See also double Lipscomb or Lipscombx2; a Lipscomb attack taking out BOTH knees at once, for added effect.

Pal: I Lipscomb'd his ass, he fell right down stairs like a bag of f***ing potatoes.
Schnal: Is he okay? I'm just kidding. Who cares? Good job.
