The state of being so drunk that one might very well begin crawling on the floor. Equally, if whilst crawling on the floor, it were suggested that you ought to play with a plastic rhinoceros, you wouldn't be opposed to it. Comparable to crunk, but referring to someone who is intoxicated to a greater extent.
Person: Hey man, I heard you started doing "crazy shit" last night, how drunk were you?
Buddy of person: Oh man, I was rhino-drunk. I'm quite hungover this morning.
