WHY DO PEOPLE CALL THE CAMPS GREEK AND ROMAN CAMP HALF-BLOOD?

I honestly have no idea... like Du said, camp half-blood is camp half-blood and camp jupiter is camp jupiter. My best guess is that either: it's just a joke. (And if it is, then it's a dumb joke) or: some idiots read the pjo series( hoo not included) and now they think they know everything and (SOMEHOW) got the two camps mixed up. I ain't saying this is right, it's just my opinion.

It could be because "half-blood" is a term for demigod. As the camps are both for demigods, that may be the reason. But, of corse, Camp Jupiter's campers can also be decedents of demigods. I honestly have no idea. It could be that we've knob Camp Half-Blood longer, therefore we call both of the camps Von that name?
