Rock-Bottom Collectable 

A possession, held by a collector, that means so much to them they would have to really experience an all-time low in life to even be tempted to part with it.

Invaders could be bombing my neighborhood intent on occupying my home, and this is the item I’m still taking with me as I flee, because I’m not parting with it unless I absolutely have to do so because I’ve otherwise hit rock-bottom, so this is my rock-bottom collectable. Alternatively:

I treasure this collectable so much, I don’t know what kind of rock-bottom scenario I would have to encounter to give this item up, I just pray I never do. Let my family sell it once I’m gone to help pay for my funeral.

Fast bottom

When a person has an unfortunate problem with regulating their own bowels.

That burger has given me a fast bottom.

cherry on the bottom situation 

A situation where you know there's something different/wrong but can't place why until afterwards. It can also be a situation where you know something could happen and is preventable, but it happens anyways.

Dave: "That's because you bitched out on Sam who was planning the party the night before."
Bob: "Damn. That's a cherry on the bottom situation."

Ben Stein Bottom 

When you are sleeping with someone and they won't try any position but missionary, while making no effort and just laying there in silence. Very boring sex, like that if you were to bang Ben Stein the Clear Eyes guy...

My date was hot, but man, were they a Ben Stein Bottom!
