People just mispronounce mine,or ask what it means. I reply, I'll usually get a "Oh...that's deep" or something similar, and I'll go back to playing.
I have seen some very unoriginal names, very frequently. I do take pride in my online identity, and respect those that also do the same. People that irk me, though, are the ones that have Game-Specific tags or "1337" styled tags; "C0D sN1p3R" and the like. Or people that have to have some form of phallic, excremental, or otherwise veiled expletive as their tag.
Tags I don't like, I don't actually insult. I just say them ad infinitum, and allow the inherent stupidity of their name choice speak for itself.
