We got evicted from our apartment and I couldn't immediately remember my password, only had it stored on my desktop PC which is still boxed up.
To answer your question, Clutter is actually my family name. Car Crash is a nickname that stuck with my high school friends after I'd become a bit of an accident magnet, while never actually being the cause I've totaled three cars and have had more than a handful of fender benders. Nothing in the past seven years though, counting my lucky stars for that.
But it's still more or less a universal username for me online. Makes it easy for other people to identify me. Which, unfortunately, works against me I suppose.
I kid you not, when the constable was coming into my apartment to evict me, I'd thought I'd said the wrong thing, maybe even on here!
