I don't think I'd ever heard this word before you used it, but it's easy to guess that it has something to do with rotate. The car-pooling example was helpful, thanks, Marianna.
I looked up interlocutor, again to confirm my guess, since this word is also unfamiliar to me, and I like the idea of being the second def.: The performer in a minstrel show who is placed midway between the end men and engages in banter with them. (Atomica) And so, to bring in the other end:

(Oh, I LOVE this place!)
