A girl who doesn't go along with Tits or GTFO, ever, despite the fact that she's on the internets. She completely disregards the rules of the internets set forth by it's founding fathers, George Washington and Samuel L. Jackson.
A bearhead is the cancer that is Rules 1 and 2. Usually she's too cute for the newfags to lecture on the rules, because she has "vampire red" hair or foxtail highlights or some shit. Essentially, she is a honey badger.
