I'll give some of mine
Mike_Messiah
(i use it for ragnarok, and guys out there really feels it cool on me, cuz i am a Vit Knight,the meat-shield,the protector..the messiah)
EdgE_Messiah
(EdgE is my clan name,so when we slug it out with korean guys at Reliance Web world, me an my gang use EdgE prefix.But recently, all these amatuers started using our clan name, saying they wannabe part of our clan. Part of our clan??..MY A$$..only the BESt gets memebrship)
Your Father
(its kinda funny you know, when u kill someone in CS, the notice comes something like -Your Farther killed XXXX, so its good to taunt ppl )
Other good ones are
Dreadnaught
Scavenger
BraveCoward
Cr33p
Despot
rookie
crackshot
Actually, the joy of LAn gaming is to use Counter-Names
Like there is this AIR clan,our stiff competitors,consisting of Snipers who snipe while running without zooming.It can get kinda frustrating.One of them, is AIR_REVENGE..So one of my teammate changed his name to AIR_POLLUTION and so on. Its all taunt and mock game
