Seamless Pantyhose 

High quality pantyhose without seams in the crotch area. The single most sexy item a woman could wear. Never should be worn with panties underneath and should be worn by all women, but only if they want their man to be turned on more than ever before.
You are not a proper pantyhose model unless you own a pair of seamless pantyhose!

Seamless Collaborative Guy Lie 

The rare /phenomenon in which each man in a room is caught in a snafu of being in the middle of a sticky situation. This causes compulsive lying where each guy builds off the other man's lie. It is the most flawless of plans because women tend to lose interest in anything men say fairly quickly. First popularized by Scrubs when Carla walked in on all the male staff watching Carla and Turk's nanny for Izzy on the television. Carla walks in, and all the men enter the Seamless Collaborative Guy Lie Zone.

“And then every male in the room felt totally in sync, resulting in the rarest of all phenomenon - the seamless collaborative guy lie.”— J.D.'s narration
“Hey baby, what are you guys watching?”— Carla

“Football.”— Turk

(Everyone agrees)

“Football? Isn't the season over?” -Carla

“And then every male in the room felt totally in sync, resulting in the rarest of all phenomenon - the seamless collaborative guy lie.”— J.D.'s narration

“The American season is over, we were watching Mexican Football.”— Keith

“They started late this year.”— Doug

“Because of the churro vendors.”— Todd

“They went on strike and the players wouldn't cross the picket line.”— Ted

“When the dispute turned violent, they called in Rodrigo Vasquez, the owner of the Baja Panditos to step in.”— J.D.

“Thanks to señor Vasquez' experience dealing with the fruit pickers unions, he was able to broker a last minute deal and the season was salvaged.”— Dr. Kelso

“And that's why we're watching football in the spring.”— Turk

Seamless 15

Similar to "Freshman 15;" when a first year investment banking analyst (usually a male) continuously maxes out his firm's SeamlessWeb allowance. This, combined with extended periods of sitting in front of a screen, high levels of stress, heavy boozing, and little to no exercise, results in a quick 15-pound weight gain.
Analyst 1: "Did you see Kevin back at Christmas? Dude got FAT!"

Analyst 2: "That's what happens when you order Chinese and buy 2 appetizers, 2 entrées, and a dessert every night just because you get to spend $30 on dinner."

Analyst 1: "Ahh... the Seamless 15."

seamless panties 

An alternative to the thong or g-string, seamless panties are a form of women's undergarment in which panty lines cannot be seen underneath tight clothing (such as leggings) as it is made up of seamless material.
Contrary to popular belief, women wear seamless panties when they *DON'T* want panty lines....they wear *thongs* when they *DO* want attention.

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.
