A scrub is someone who is so god damn stupid that they drop the IQ of everyone they look at. They usually make terrible puns and really lame, overused inside jokes that nobody thinks are funny. They have high, ear-piercing voices that shatter ear drums. They have no friends and they are generally found camping on Call of Duty with a K/D of 0.1 or on Minecraft building random, ugly-ass shit.
Scrub: "OMG THIS GAME IS RIGGED! WHAT THE HELL!!!"
Person: "JESUS CHRIST, KILL YOURSELF, SCRUB. YOU'RE STRAIGHT GARBAGE! GO DRINK SOME BLEACH!
