Bottoming Out 

To "bottom out" is when one is having sex and the penis reaches the cervix, or the top part of the vagina, and can go no deeper. This can be referred to as "bottoming out," or in the past tense as "bottomed out."

It can be either painful or pleasurable, depending on the girl and how extreme the bottoming out is.
Man, I was fucking this chick last night and she told me to stop cause my dick was so big I was bottoming out on her.

Bottoming-out 

Bottoming-out.
Known to happen to those of us with low-riding vehicles when we underestimate a speed bump or curb and --*eeeeesh!*-- end up momentarily having the speed bump or cub bump up kinda hard against the tender underbelly of our vehicle.

This term has another, newer, meaning though and of course it's a sex one.

"Bottoming-out" in bed is also when a woman is straddling her male partner and, only when her partner has a long-ish member, she tries to go deep and rest herself on top of his hips but *-eeeeesh!-* it's too long and the tender underbelly (her cervix or just the dead end of her birth canal, so-to-speak) is bumped kinda hard up against by the aforementioned member.

Women make the same exact face when either happens.

Bottoming-out.
I'm a little bit sore this morning after bottoming-out a few times last night with Ryan, dude. Eeesh!

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
