2.
An italian male who lives in New Jersey. Guittos use tanning beds daily and go to the gym daily. They tweaze their eyebrows and sometimes they draw them on. Some guittos have gone to the extent of layering 4 polos and popping each collar. To get ready for a night on the town, which is everyday, a guitto will mousse, gel and spray his hair and dab on a layer of lipgloss for plump lips. Guittos go ga-ga over a great bandana and own several dozens. Completely materialistic, yet a great friend if you love douches.
Guitto: "Hey dude, how are my lips? They good? Yeah? OK. What about my hair? do you like the spikes. Ugh, ill just go check the mirror."
