Boun

Boun is one extraordinary guy. He might seem cold at first, but once you get to know him, he is warm, fluffy, caring, genuine and funny. He loves his pao, friends, fans and family. A boun can be very cheeky at times. He's really softhearted if you get to know him. Unlike other boys, Boun is different ent and will stand out compare to most people. Mainly because of his ethereal looks and his soothing, healing voice. And be careful, he has a dangerous side... Boun oftens does not wear clothes under his blazer causing nosebleeds to happen. He isn't interested in any guys except for his salapao. Can be clingy, possessive but most of the time lovable. In the end, he is a cool, lovable, humble, down to earth guy that deserves the whole world. Stan Boun Noppanut Guntachai.

Boul 

This is a Philadelphian slang term used instead of saying "guy." A lot of the time, a "boul" is someone's friend, or peer. Dude; friend; man.
