I am in your base killing your d00ds is a catchphrase that can be roughly translated to "LOL you got pwned and don't even know it yet." It originated in on-line multiplayer games such as Command and Conquer. While player one was innocently building tesla coils and general infantry, player two is in player one's base, killing his d00ds. Player one doesn't even notice, so player two sends him a message:
I am in your base killing your d00ds.
Teh origin of this meme
Two players (one unnamed, the other known as 1337h4x (leetspeak for "f*cking Nerd") are in a game of Starcraft, with 1337h4x playing as the Zerg race, and the other as either the Terran or Protoss races. 1337h4x Zerg-rushed his opponent, and on finding that he was getting raped, his opponent asked:
<n00b>dude, where are you?
<1337h4x> im in ur base, killing ur d00ds

The real trouble with reality is that there's no background music.
