I figure, being new here, I'll throw in my own two cents. I used to use the nickname "Smegalicious," until I realized people kept either being disgusted or making jokes about Red Dwarf, which (I am a little shamed to admit) I am not actually familiar with. So I changed to my current user name, which I stole from a short pun I read somewhere.
Word of the day: ignoranus, noun, someone who is both stupid AND an asshole.
I just find it amusing.
