Anyone with that last name is cool. They are also fun, caring, and great at sports. They are very attractive, and if you know one you're blessed. They are most always popular, and nice. They are strong-willed and sarcastic, but do not forget that they will take the shirt off their back if you need it, even if they complain they're cold. You can always trust a Guglielmo!

Basically omniscient, especially when it comes to judging buildings in NYC. Sexy AF, loving and warm, with a Guglielmo you always learn something about architecture. Guglielmos, pronounced Goo-Yell-mo, usually live on upper floors where they can assess and check construction sites on the street below and update their friends on any progress. Everybody loves them, Guglielmos are a rare blessing that only few are so lucky to have in their lives.
What would a Guglielmo say about Hudson Yards?
