A name used to reference a total stalker.
A Karl has at least 6
restraining orders on his record due to crimes such as computer hacking,
breaking and entering, and creating full shrines of a particular girl in his room. He would steal dirty underwear and collect hair from a drain. Can be spotted due to a not so inconspicuous unibrow.

Karl aren't you?...And

unibrow, that's disgusting."
