im in ur base killin ur doods
Strategy game fans are notorious for their bravado, taunting each other while decimating entire armies in the name of glory. Nothing is more horrifying than knowing your opponent has infiltrated your fortifications and is destroying your forces.
Of course, this is made all the more embarrassing when your enemy makes you aware of this with an annoying 1337speak phrase. The phrase hit memetic levels when it started getting repurposed for all sorts of actions.
