Refers to a tactic in competitive online games that feature a mechanic where players come back to the playfield a few seconds after they're killed (called respawning). There are usually only a few points on the map where players respawn (called "spawn points"), so some players pursue a strategy where they wait near a spawn point for an opportunity to kill any respawning players before they get their bearings. So kitty here is going to wait for the wings to be done and then snatch them the instant they "spawn" from the oven (or fryer or what have you). (Edited for spelling.)
