Weirdest Reason For AFK?

[Ryuko]

I used to play online games with a German friend, so the keys on his keyboard were in a different position. (That is relevant to the story.)

I once said: brb for a sex
What I meant was: brb for a sec

The x and c are next to each other. He did not know that. He was thoroughly confused.

As far as a more 'realistic' thing I've said in party... "Brb, need to put my bird to bed." (I have a pet bird. He likes to be covered at night. If I don't comply at exactly 10pm, he starts saying... "It's bed. Y'ready? Ready? It's bed! Go in. It's beeeeeeeeed..." over and over again and won't shut up. XD)
