 * On accidental consumption: when you somehow end up eating an item accidentally (currently, this is used for when items are hidden in food like bread or cake)
 *
 * The base proc will check if the item is sharp and has a decent force.
 * Then, it checks the item's mat datums for the effects it applies afterwards.
 * Then, it checks tiny items.
 * After all that, it returns TRUE if the item is set to be discovered. Otherwise, it returns FALSE.
 *
 * This works similarily to /suicide_act: if you want an item to have a unique interaction, go to that item
 * and give it an /on_accidental_consumption proc override. For a simple example of this, check out the nuke disk.
 *
 * Arguments
 * * M - the mob accidentally consuming the item
 * * user - the mob feeding M the item - usually, it's the same as M
 * * source_item - the item that held the item being consumed - bread, cake, etc
 * * discover_after - if the item will be discovered after being chomped (FALSE will usually mean it was swallowed, TRUE will usually mean it was bitten into and discovered)
