The Thompson submachinegun had several nicknames, one of which was the Chicago Typewriter, specifically with the fore grip and drum mag. I was born in Texas, and everyone knows everything's bigger in Texas. TexasTypewriter, implying a HONKIN HUGE MACHINE GUN, because I love filling things with bullets until they're dead three times over. No space, because back when I played Xbox live there was only just enough space for the letters.
