"
Im in ur (noun), (verb) ur (noun)" actually started back in the days of
Command and Conquer. When playing against other human players, occasionly one player may say to the other "Im in ur base, killing ur
doodz" as in meaning "I'm in you're base, killing your units, and you don't know!" It wasn't untill CounterStrike did the 'craze' actually be known.
