Homecoming (or public testing) hitboxes is a phrase most commonly used in the Roblox fighting-party moab game community Project Submus Accudo fan base when a attack (usually a melee) does not register when it should. This being a direct reference to the first public test build for 1.0 (or the full release of the game/homecoming update) where there was a bug in the hitboxes that didnt register most melee attacks and/or delayed them, making most of the brawlers and assassins unviable. This bug was fixed after the developers break ended along with the other bugs in public testing build/demo 1

A euphemism for “kill me” now that composting oneself after one’s death has become popular.
