Muscle found on the top half of the arm, made up of the long head and the short head muscular bundles. Both link in to the elbow joint and both link in to different parts of the scapula, or shoulder blade, for those unfamiliar with the precise workings of that most noblest and erotic of things: the shoulder.

One of the easiest muscles to develop in bodybuilding training.

Culturally an important thing for men to cultivate, if he ain't got no biceps he ain't gonna be helpin you move that couch. Flexes the elbow and looks impressive. If you want to spend hours on it. Hours that could be spent fellating the neighbour's dog.

Despite the prominence of the bicep muscle it plays little role in actual strength and punching power, as far as the arm is concerned the triceps muscles are far more powerful as they are made up of three, larger heads and move both the shoulder and forearm.

The biceps maketh the man. Biceps are made not born.
If you were a bicep you'd want to be big and powerful wouldn't you. Remember that.
You couldn't own Paris Hilton in a fight

Sure I could, in fact, if i put you in a chokehold then flexed my bicep your head would pop off. *flexes mighty biceps*

I stand corrected *shits self, runs away*

----

With biceps like these I can pull any girl I want

Or you can pull any girl with a brain as small as your pathetic excuse for guns.

----

Hulk Hogan has heroically mighty biceps that could crush the skull of any would-be burglar or celebrity.

"I have 18 inch biceps" 

A common claim among bodybuilding enthusiasts who usually weigh between 165-180 pounds. Most of them, of course, are lying.
Small guy with 15" biceps looks at 6'0 215 pound fitness model Bill Davey, who has 18" arms.

"Yeah man, that guys huge. But. "I have 18 inch biceps" too, so he's not that big."

Baseball Biceps 

A condition where the biceps of a person are malformed to resemble baseballs, caused by improper exercising techniques. Usually this happens when a person half-extends their arm when exercising over a period of time. For example, on a chin-up bar, the person never lowers their body below the half-way point (the farthest they extend makes their arms look "L" shaped). Once acquired, this condition is very difficult to correct. Not only does it limit the person's lifting potential, it looks unattractive to most people.
Hey check out that meat head over there, his baseball biceps look ugly as hell.

I'd better be careful of my lifting technique or I might be stricken with the infamous baseball biceps.

God damnit, I have baseball biceps. Welp, time for amputation.

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
