I voted 'not a cartridge'
If I was going to be a tool like Sinistron and just go blindly along with the dictionary definition, I'd have to agree that HuCards are cartridges... but no...
HuCards are a separate identity. Dictionary definitions don't have to be set in stone, and can be changed by a dedicated group of people... HuCards shouldn't be lumped together with those clunky space wasters that, as Ceti pointed out, need you to blow on em half the time before they work.
One word that has had it's original meaning corrupted is the term "semite"
According to the dictionary, the term "semite" includes a number of Afro-Asiatic linguistic groups, including Hebrew, Arabic, Aramaic, Ethiopic, and some others... but the definition has been corrupted by Zionists to refer exclusively to Jews... to the point that when people say "anti-semitism" it is understood that it is Jews who are being talked about and not any of the other "semites"
