Guidonaut 

A guidonaut is the rarest form of guido. Much like regular guido's, guidonaut's use so much hair product that it disrupts their normal brain function. These guido's think they are the greatest thing in the universe, because if you let them talk long enough they will likely tell you they have been to space. Guidonaut's are generally rude to male's and downright degrading to women, especially of foreign descent.

Woman: Guess what I got on my test?
Guidonaut: I don't care! Look at my hair.
Woman: 95%
GN: What you beat me, how is that possible, your a woman.
Woman: Excuse me.
GN: Yah well, it doesn't matter, I have been to outerspace in my VeeDub rocketship!!!
