Cock_blocked is what I thought of first, but refresh_blocked has more uses. Basically anytime that a yukkuri would perform an activate that would be refreshing that a person or yukkuri interrupted for any reason could be a refresh_blocked.
I translated one a while back where a Reimu and Marisa were trying to refresh but everytime they were about to climax (shout "refreshed!") a tape recorder said "take it easy!" forcing them to stop refreshing and respond back. By the end they were like "why wont you let us refresh?" I cant seem to find it though
