All kinda lame :( but i think frosty

Frosty boooyy

Frosty is the best one there, but I have an even better one for you to use (for free, no less), and this gamertag is HairyBurrito

I think flipside is the coolest. All the others make you sound like you're ten.

i like Frosty cause its OG (original) Doesn't include Xx or numbers just plain and simple.

How about FlipsideTurner

I like sqiderbyte!

Make it something funny. all those are lame.
