grundle assist

The act of pressing on ones taint, in an effort to aid in the movement of extremely large, and rock hard turds.

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.

I need a shower. My grundle grease has gone sour.
