Wikipedia explains the subtext...

Funny. Simply funny! I use Trillian to get my MSN, Aim, ICQ and yahoo- chats in one window. Quite handy. In the newest edition they added at feature that's looking up phrases on the original edition of Wikipedia. As I said - quite handy if you're operating in many languages, use abbreviations and else - but in times a bit baffling when chatting in my mother tongue. For example the short "hehe" means a kind of (evilish) laughter in German - Wikipedia looks it up as a bantu tribe. Hehe!
