guidoo 

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.

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!
