A person possessing a wild and untamable "bush" atop their head, often a demon nincompoop and a skilled sandwich maker. To use this term properly, one must precede this noun with some sort of vulgar adjective. Bush heads are not to be confused with Jew-fros, which are the more visually appealing and all-around better version.
Jessica: OMG i totally tripped up the stairs after making you a sandwich.
Devon: Seriously, why are you such a demon bush head?
