unintelligent hair 

Hair where a certain section of it protrudes in an abnormal and down right creepy fashion, to the extent that it makes that person and everyone around him/HER feel and act retarded. This usually results in everyone screaming nonsensical things and attempt to push down the strange hair.

Girl: OMG Michael look at Yocelyns' unintelligent hair. ELIOT!
Boy: I know every time I look at it I want to push it down. PADOODELY!
Girl: Me too but she wont let me. SKEDOOSH!
