That time generally starting a few days before Thanksgiving and ending sometime after the New Year where everyone appears to lose all common sense. Highlighted by events such as Black Friday, Drunk Christmas Parties, Fights over parking stalls at malls, erratic driving on freeways, an unexplainable increase in the number of people out and about, and general chaos wherever people tend to congregate.
Dude this sucks. I try to go to a store and I get hit by the Forty-Five Days of Stupid. People cutting me off on the drive over, fights over a parking stall, crabby-ass folks in line at the check out, and clerks that look like they would rather kill you and stick you in a closet than ring up your tab.
I'm gonna go in the basement with a six-pack and wait it out.
