Guido hair. Typically a shiny and greasy vertical spike-style, the guidoo wearer looks much like a confused farmer who has just successfully milked a bull. Guidoos vary in length from year to year but are always very greasy. Must contain no less than 2 different haircare products. Must take at least 20 minutes to orchestrate.
With his blistering forehead acne and his shiny new Guidoo, Chet looked as if he'd been bobbing for french fries.

Guido Pump 

The greatest of all arm workouts. Typically done on Friday and/or Saturday, the guido pump consists of fifteen to twenty sets of bicep tricep supersets. One should drink pre workout prior to a guido pump and throw on their smallest shirt immediately afterwards.
I did the guido pump last night, and was feeling juicy as fuck afterwards. My arms were hugging the sleeves so fucking tight.

guido tuxedo

A tracksuit or warm-up suit. While intended for athletes to wear while on the sidelines at sports events, the guido has adopted the tracksuit as a integral part of his wardrobe. The top portion of the tuxedo should never be zipped up beyond the bottom reaches of the pectoral area of the torso, and is best complimented by an oversized gold crucifix. It can be worn alone, or with a plain white wifebeater, the only acceptable undergarment.
Ahh, yeah... nice guido tuxedo, man. Please tell me you're on your way to the gym or breakdancing lessons or something.

Behold! Let me tell you a bit about French GUILLOM, since you seem to be interested! French GUILLOM is something ethereal! Something that cannot be described to words! It's...it's simply unanalyzable! You see, the thing about French GUILLOM is that we only know little to nothing about this "entity" as you call it. We know for certain:

1. it's French.

2. It can speak French, but has made the impression to us, GUILLOM researchers, that it's too withdrawn to have the courage to speak French, so it weirdly acts like it's Spanish instead (which we, GUILLOM researchers, highly doubt).

3. It is an object-sexual individual, from many precise investigations and reports that delineate instances of him trying to insert his penis into the structure of the Eiffel Tower, perhaps because it thought it could impregnate it.

4. It's intangible, which means it's unable to be touched and doesn't have a physical presence, though we are aware of his presence because of a special device we created called the G.D, and no, it doesn't stand for Gaucher Disease, but GUILLOM DETECTOR.
5. It appears to be a hermaphrodite, meaning it has both male and female sex organs! We were surprised to discover when we were attempting to scrutinize its existence using the GUILLOM DETECTOR, it isn't a male, for we've also found that it has a vagina and 6 breasts! Fascinating, isn't it? GUILLOM truly is an astounding creation of nature! We've never seen something like it before, in our entire lifetime!

Guidosis 

A condition caused by watching too much Jersey Shore or going to clubs infested with too many guidos and guidettes. Similar to zombie-ism. Orange spray tan may rub off on you, you may find yourself doing the guido first pump, turning up your collar on your white shirt, talking like a douche or picking up skanky bleached blondes or guidettes.
One dude to another: I have a ranging hangover and I woke up with my bluetooth in my ear and there was orange spray tan on my white shirt and the collar was up! WTF!!

Another: We can never go to that club again. You've got guidosis. Jump in the shower and scrub down now!

More from Urban Dictionary
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.
