That Guido is getting attacked by a Grenade.

A sad excuse for a male. Guido's spend most of their time at the Jersey shore at a bar called Dejays. There, you can find them pounding yegabombs and hitting on under age girls. The guido attire consists of shirts two sizes too small. They will then pop the collar on their shirt and undo about three or so buttons to reveal their shaven and tanned (sometimes with ingrown hairs) chest. Guidos will wear sunglasses not just during the day but also at night and inside dark night clubs. This makes them feel cool and "gangsta". They are usually involved in many violent attacks where usually 10 of them will jump one single person. This is due to their rage brought on by growth hormones and steroid which have an effect on their already undeveloped brains. Also known as Douche bags, the guido will idolize TV shows such as The Sopranos or Entourage and will try to impress douche bag girls with their Tony Montana (AlPacino in Scarface) impersonation. As mentioned before, it is best not look directly at them as this will make them feel threatened, and because they have usually overdosed on Protein powder and steroids, they may become violent and initiate a fight for no reason at all.
" Eww look at that Guido..he's all prickly. He obviously didn't shave his chest and arms today."

"What a douche"

A normally tan individual that is constantly thinking about himself and ways to make him appear cool, such as: Going to the gym, Taking a variety of vitamins and supplements, Tanning, Constantly grooming his blowout/facial hair, Partaking in an excessive amount of photos, Clubbing, Wearing very expensive/tight clothing, Bragging
Look at that fuckin guido, he has over 1,500 pictures on facebook and hes making the same face in everyone.

Basically, that guy at the gym who:

- Begins screaming wildly while lifting 130 lbs.
- Lugs a 1 gallon water jug around, but never seems to drink it.
- Hits on anything that moves
- Obsesses with weight lifting, and takes Muscle Milk, Powerbars, or any other body building suppliment.
- Screams slogans while lifting weights, like "Feel da powa!"
Andrew is such a fucking guido. He was ejected from the gym for wearing sunglasses inside, and yelling that his workout partner should push "like his mother pushed him out of the womb." (True guido experience)

spends a lot of time getting ready in front of the mirror (probably longer than a woman), has enormous amounts of gel in his hair, wears a tight t-shirt or wife-beater and somehow eventually ends up with his shirt off. Ed Hardy shirts are preferred but if you're a poor guido Affliction shirts will do the trick. Other essential fashion accessories include designer sunglasses, gaudy jewelry (earrings, necklaces) and torn, stonewashed/white jeans. Steroids are almost a must and you must work out while looking into a mirror at all times. Over-Tanning is essential and a preferred look is an oompa-loompa shade of orange.The guido is very much into his looks, has a large ego, very proud of his italian ancestry, and very much into techno/euro-trance/beats music. This form of music gives way to the guido fist-pump and other forms of gyration. Guidos can dance anywhere including - but not limited to- parking lots and beaches. When guidos go out to party they engage in binge drinking, lame come-ons to anyone of the opposite sex, the guido-fist pump/dance off and the eventual roid-rage fight at the end of the night.
These guidos at the beach are cracking me up with their dancing.
