When farmers get lonely (once their daughters move out), sometimes they will shuck an ear of corn, and insert said ear into their own/acquaintance's/mistress/pig's anus. Shuck fuck.
I done been so lonely since Carla Jean went off to work at Uncle Limpy's Hump Palace, that I had to resort to shuck fuckin! But there ain't no amount o' corn that can shuck fuck my depression away...
(verb) the act of having sex in a corn maze.
“Yo Stephanie, we're in a corn maze...now's the perfect opportunity to shuck fuck 😎😩”
