Stupidcasm is the pretending of one's own ignorance to "shut-down" a know-it-all friend, who is trying to correct your false stupidity. There are different shades of stupidcasm to better fool the victim...
Stupidcasm in action:

("I Wanna Hold Your Hand" is playing on the radio in the car)

Dude 1: "Man, I love the Kinks"

Dude 2: "Actually, dude, the song playing on the radio is none other than "I Wanna Hold Your Hand" by the Beatles." drifts off into an intellectual rant with a glazed look in his eyes..."this song is from 1963, and is one of the two songs the Beatles sung in a language other than English..."

Dude 1: Interrupts "I was just messing with you, man. Of Course i know who sings this. Dork."

Dude 2: "I hate you and your stupid stupidcasm."
