No. I only insult my friends in real life. Plus I haven't played an online game since Fallout Tactics had the free demo. We'd log into games that said "NO MINES" and naturally be miners. It was hilarious!
Nothing really mean, usually just 'b****' or 'you cow' etc when we fight other teams and the the other person wins or whatever. Then we both laugh and move on.
Generally the sort of insult I'll yell at the other team, but nothing actual in bad spirits or hateful. --- RENAMON!! *weeping* YOU HAVEN'T BENT ANYONE OVER THE SINK AND SHOVED A "CHECK THE STICKY* UP THEIR ASS IN MONTHS!! *curls into ball crying*- Cither3000
