IBB 

I'll Be Back, IBB instead of BRB.

Chatroomguy1:Hey I gotta go but I'll be back.
Chatroomguy2:Why didn't you just say IBB?
Chatroomguy1:What does IBB mean?
Chatroomguy2:It means I'll be back, it's just easier to say IBB, so next time you have to leave but will be right back just say that, we will know what you're talking about.
Chatroomguy1:Ok, IBB.
