Another Deja Vu...
So an old school Star Wars MMO had a language mechanic, that if yo didn't know another players language it would show up somthing like this "%^&%&%&*^%&*%".
So our guild all made Wookies on a different server (Mine was DR Zaus, the Wookie that looked like a Silver-back Ape). We went strait for the cantina for some hi-jinx.
Wookie line dancing, crazy antics, and....
....since we were all in Team Speak we would type garbage into the chat to confuse people.
"What language is that?", "Why can't I understand it?"
