scrubzilla
someone who is a super-huge monster scrub, someone who perfectly epitomizes every possible definition of scrub, and sucks at life sooo hard that they dwarf all other scrubs and could come out of the ocean and destroy the scrub city with their scrubliness. 
Person 1: Janee got arrested, kicked out of school, lost her job,  and moved back in with her parents.
Person 2: Damn what a SCRUBZILLA!
