What does BI5 stand for in chat and texts?

Back in five

When someone says they'll be BI5, it means they'll be "back in five." In online chat, people use this acronym when they have to go AFK, but expect to be back in five minutes (or less).

In texts, people sometimes use BI5 to state they'll physically return in five minutes. For example, if your SO just left a party and is on their way home, they may text you "leaving now, BI5."
