in Inform text adventures, it is not uncommon to limit the number of items the player can hold at once, but then also give them a backpack or other kind of container that can hold an unlimited number of items. (i don't know the motivation for this; i suppose it encourages you to put useless junk somewhere and not keep getting distracted by it?)
anyway
in the hitchhiker's guide to the galaxy text adventure, which is infamously goofy and tricky, there is such a container, which douglas adams boldly named:
the thing your aunt gave you that you don't know what it is
and you can in fact refer to it like that. by its full name. every time. if you want.
savvier IF players will just call it thing though
