The ass of a chubby person, specifically pertaining to the creases and dimples that make the skin resemble a walnut.
That girl rode me good, but I won't be calling her back - she has a real walnut bottom.
Someone who admins that they're a bottom and has no problem with it (is sometimes even proud of it) is called King Bottom.
Person A: "You are such a bottom! Every switch compared with you seems like a top."
Person B: "I know. I'm a bottom. Do you have something against bottoms??"
Person A: "So you like being a bottom?"
Person B: " Yeah, I'm the King Bottom!!"
When on tour or traveling, you use the last pair of socks in your luggage and all the socks left are smelly.
Touring during the summer is the worst. I only made it to San Francisco before I hit sock bottom.
In contrast to "turtles all the way down", an expression of the problem of infinite regress, the "bottom turtle" is the foundation upon which everything else is built.
An example from computer security:
You have some software with a secret that you need to protect, so you encrypt it. Now you have a key, which is really another kind of secret that you need to protect, so you encrypt it, and so it becomes turtles all the way down. To break this loop, we need to establish a bottom turtle. There must be a secure root of trust either in hardware or a trusted external system upon which the security of the system is built.
To break the loop of infinite regress we need to establish the bottom turtle.
A crippling bottom is a sexually passive and submissive individual that prefers to receive rather than give sexual stimulation. Crippling bottoms differ from regular bottoms in that they get annoyed an irritated when sexy people that look domineering, turn out to be a raging masochist. An example of this would be Julian Devorak from The Arcana: A Mystic Romance, the free mystery romance visual novella by Nix Hydra. Julian is a sexy 6’4 fugitive plague doctor with long leather gloves and a mysterious aura. Contradictory to his appearance and attitude, Julian never shuts up about how much he wants to get stepped on. Crippling Bottoms are irritated by such things.
“Why is Maggie so mad?”
“She found out Rico is a hardcore masochist.”
“Haha! She’s a Crippling Bottom!”

Allan: "Oh. Well, what toppings do you like on your pie?"
Zito: "Nothing at all. I never eat pizza with anything on top. Just cheese and tomato sauce."
Allan: "Nothing on top? EVER? You're such a pizza bottom!!"
