Bake up by Goddessofloco August 22, 2014
When you're with someone; hanging out a lot, kissing, making plans, and are exclusive but are choosing not to date or aren't able to date because of circumstances. If you are baed up, it is understood that you are not looking for a boyfriend/girlfriend because you have someone in your life already.
Mark and I know that in a few months he will be leaving for college so we shouldn't make a big deal out of dating; but that didn't stop us from getting baed up for the summer at least.

bake up call

Requesting a hotel, typically a motel, to call you at a certain time to remind you to smoke the doobage. Essentially a wake up call for stoners.
My roommate Carson used to set the alarm clock to wake him up for a smoke session early in the am, aka wake n bake, so much so that when he travelled and was too high to figure out how to set the alarm clock in a hotel, he'd call the front desk and request a bake up call. Typically at 4:20am.

babed up 

When an already very attractive female female puts in extra effort to make herself even more attractive or a "babe."
You're at a wedding and see a bridesmaid who you've been longtime friends with. You've always thought she was very attractive and numerous friends have agreed with this opinion, solidifying her attractiveness in the eyes of men. At this wedding she has gotten her hair and makeup done professionally, furiously worked out for the big day, and the bridesmaids dress surprisingly didn't ruin all of her effort. She babed up. All of this has made this typically "very attractive" female a complete and utter babe, hottie, smokeshow, etc. This could also be defined as a female who may be rated a 7 or 8 being transformed into a 9 or 10.

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.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
