To peek over the shoulder of the person in front of you in order to catch a glimpse of cock.
1. Tom got a black eye from cock craning for too long in the gents.
2. It took Bob a while to notice that Tony was cock craning behind him.
3. No-one in the polaroid photo could work out who the thin man cock craning behind them was.
