During the fall, winter, and spring, you will most likely find him working in the food service industry or doing some kind of construction. When not working, he will spend his time at the gym lifting weights in anticipation of summer or visiting a tanning salon until he gets an unnatural shade of brown (or orange if he self tans because he has a bodybuilding contest this weekend in Atlantic City). Some say he is nocturnal because he is spotted at dance clubs every evening that focus exclusively on club, house, hip-hop, or eurotrash music. His favorite dance move is the guido fist pump which consists of pumping a clenched fist in the air to the beat of the music as you take off your shirt to show off your unnaturally tan and ‘roid ripped body. His drink of choice is Miller/Bud Lite or anything that contains either Jägermeister or Red Bull.
He is very easy to spot. As already mentioned, he will be unusually tan or orange in color and muscular from being an amateur body builder. His hair will be exceptionally gelled and almost certainly spiked up. He will be wearing some kind of gold chain around his neck and oversized fake diamond earrings in both ears he most likely borrowed from his guidette sister. His outfit consists of designer name brand jeans or trackpants and a shirt with a zipper that is so tight that it must have been bought at Baby Gap for Guidos (otherwise he wears a tanktop, an unbuttoned shirt, or no shirt at all). When a picture is taken of him, he most likely leans back and puckers his lips for no apparent reason.
If you are still unsure how to spot him, see the excellent documentary Guido Beach.
