When two or more men hang out so much that they have to shit at the same time.

I have to shit too, we must man cycling.

Mancycling

When a man is so robbed of nutrients that he resorts to ejaculating in his own mouth, for the little value it has.

"Oh man, I was watching the discovery channel and some guy was mancycling because our aid didn't get there soon enough"
