Gamers use WYB as shorthand for "watch your back." This acronym may be an entreaty (e.g. "WYB, we can't keep feeding the other team.") or a threat (e.g. "WYB, I'm coming for you."). When playing a multiplayer game, your teammates may also tell you they are going to WYB - which means they'll do their best to protect you from enemies.
