Top Definition
A teenage girl that spazzes out and goes psycho on a daily basis over the upcoming senior prom. It is hauntingly similar to a bridezilla that is also a prima donna but on a larger scale.
That damn promzilla had better shut the fuck up pretty soon about her prom dress not being perfect. Who cares, it's just going to wind up an expensive cum-bucket anyway.
