Once fabled as the deepest you could get, balls deep has been surpassed by gooch deep. Gooch deep is where you go in so deep into an orifice, that you are able to shove your balls into said orifice as well, so you are no longer bound by the limiters that are your testicles. Being gooch deep means that your gooch is now touching the rim of the hole that you are pleasuring(or punishing).

During sexual intercourse, the point at where a man is fully up to the hilt and his bollocks (or taters - short for 'potatos') are touching the labia.
I was with your mum last night. My god, I was taters deep and still not touching the sides. If I hadn't have strapped a plank to my arse, I would have fallen in.

When you go so deep into the pussy that you go beyond balls deep. In this situation, a mans testicles actually enter the vaginal cavity, and he is then "up to his grundle" (the taint) in her vagina. Essentially, his testicles become the functional equivalent of Volvo crash impact dummies against her cervical membrane.
Yo son, I hyperthrusted this broad and ended up grundle deep. She screamed out that she wished she had a cervical air bag!

When you're so far up that wet hatchet wound that your knuckles are bangin' on those beef lips like a drum.
