Used by gamers to let their party members know they are taking a small bathroom break.

Party members walk up to the boss room
The healer really has to pee
"Guys brb bio" - The Healer
"Ok np" - The tank
"What?" - The rogue
"She will be right back, bathroom break" - The Tank
"What's bio?" - The fighter
"It means Bathroom In and Out, and sometimes biology, because nature is calling" - The Tank
