greasy grundle gamble 

A sexual endeavor in which the woman applies lube to her grundle (aka gooch, taint). The penis is then rammed forcefully into the midpoint of her grundle (equidistant from the anus and vagina). The gamble that ensues is legendary, in which the penis slides into either the vagina or anus.
The greasy grundle gamble is irreversible; once fate has chosen a hole, you must stick with it for the remainder of the intercourse.

I took the greasy grundle gamble with Shelley last night; it was my first poopydick!

Grundle Grab

Where the victim gets grabbed by the gooch and is tipped forward while you pull their genitalia in an upwards motion (like a chainsaw).

Man, Ree Ree just did the grundle grab on me again! That's the fifth one this lunch time.

Went to take a shit today and started giving birth to a 4 day old brick that was as long as a 20oz can of red bull. Had pull out the grundle assist. That was the last time I ate a whole plate of Mac and Cheese from there.

Grundle Surfing 

When you're having sex with a girl and you pop out, but try to get back in without using your hands, resulting in sliding on her grundle continuously, or surfing.

Man, I was fucking her and slipped out, but I was too lazy to use my hands so I was just grundle surfing for a bit until I got it back in.
