1.
Verb- The act of placing your hand with another mans hand and forming an open hole in the middle, and place your both of you penises in the hole, pushing in and out, back and forth in a rocking motion similar to a see-saw.

If done correctly it should look like your cross-cutting a log. thusly giving you the name cross-cutting
Me and joe are to cross-cutting tonight until we ejaculate in each others hands.
