Get the proto-thrash metalmug. 
Proto is short for Prototype, and is a nickname given the most handsome and sexy male you have seen. This guy would win the superlatives “best looking,” “best all around,” and “take home to mom” if superlatives were given to young professionals 20-40 years old. He’s so hot and all around great, that it is hard to believe he is real. Other males should strive to be like him.
“Proto, you look really hot today”
“Proto, do you want bacon with your French toast?”
“The guy on the stairmaster is a total Proto”
