Ok your asking what is a Oc hog?
This is the chick or dude that makes a new oc every time a opposite gendered oc joins a rp.
Or her one oc wants all the males.

Generally they do this for smut at times and wonder why players in there rp are dwindling and or dropping out.

This generally ticks off other players who want a little romance or players who get irritated by not enough non fluff or non smut

Also then you have the issue of too many ocs to keep track of.
