I always find it entertaining when people type silly things like "QQ," mostly because it helps me differentiate between people who take the game too seriously and people who play for fun.
I troll in thor_v03 a lot and I always run into people who complain about other people using Yggdrasilberries to heal while they're getting beaten up. "LULZ U CAN ONLY WIN WITH YGGZ," etc. They are pretty darn spammable. I played one server where there was a 10 second cooldown so you couldn't just mash your ygg hotkey to constantly heal yourself.
But hey, I don't care, I play for fun. If someone is being big enough of a jerk to come find me just to kill me over and over I don't mind logging off and doing something else.
"w8 me," though, is incredibly broken English. If I owned my own server I would probably ban people that typed like idiots. But that would have to be my own server that I created the rules for.
Oh, and to answer your question OP: vidya games and Internets are serious business.
