To conduct love making in a manner that is wild, passionate, animalistic, and perhaps even humorous. Lovemaking as a primitive, resonant visceral experience.
(Mutual fulfillment seems to be a key component of monkeylove, versus a rape or mindless coitus in which only the guy gets anything out of it.)
Somewhat related to the idea in the Cool & The Gang song, "Jungle Boogy".
she came over and we made sweet, torrid monkeylove
Monkeylove is referred to as gay sex between two guys.
Did you hear gay Johnny talking about all the monkeylove he got last night.
