The act of making your gal shart herself by spiking with laxatives followed by anal sex. A break-up move. Best if performed in an alternate location or one other than your place. Guaranteed that no female will ask why you haven't called her back.
My chick was starting to get clingy and suggested we move in together so I gave her a New Brunswick Mud Cutter. She hasn't called me in 2 weeks.
A variation of the New Brunswick Mud Cutter with the addiion of a double penetration either with another partner or a foreign object most notably a miniature Baseball Bat commonly sold at Baseball games.
I was going to give my girlfriend a New Brunswick Mud Cutter but my best friend came over and we gave her an Oh Henry! instead. He was stoked!
