Code 88

When you are gaming and your spouse/GF/Partner shouts to come downstairs or do something and you need to quickly notify your gaming friends you are AFK.

Friend A (voip): Cover me, going in.
Friend B (voip): Target on the left.
You: Sorry, Code 88.
*audible sound of headset being thrown down*
Friend A (voip): Sh*t his GF needs him.
Friend B (voip): Yeah, we lost him.
