Nickname for a person who is mentally unstable, batshit crazy, and hates being called a racist or fascist. Has both the mindset and musical taste of an 11 year old. Has friends in high places.
Girl, I was with Kim last night, all up in da club, and all of a sudden they started playing the latest Jesse jam, and she went crazy. I'm talkin' Gnarls Barkley crazy, not Patsy Cline crazy. What a CrunkCrazy4Nsync.

Overly emotional grown woman who cries at the drop of a hat, has the mind and musical taste of an 11 year old, and does not kill Jews, gays, or gypsies.
"Last night at the BSB concert I met up with CrunkCrazy4Nsync. Damn, that girl's fucked up in the head."
