Okay, say you're in a rookies and have no alliance. There are now 6 of you left, the remaining 5 people are definitely in an alliance.
When one of them gets hoh, and you 'inb4 I'm nommed' it means you know you're going to go up and say it before it happens. Hopefully hypothetical you will have pov, though.
Or ummm, if you pick on Streeter he used the -_- face and sometimes people say inb4 -_- because we know he will. Sleepy me is not good at explaining. Sorry.
