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!
