A man of usually European decent; usually very wealthy, handsome, charming, and abnormally sweet.

Demetreus's are ALWAYS phenominal in bed and ridiculously well hung. They have a broad sense of humor and excellent fashion sense.
Demetreus's usually have the uncanny ability to seduce just about anyone they want to. Women, men...whatever they like. However, they arent usually in steady relationships long. Demetreus's love to travel and can't afford to be held down.

Chealse: How would you know?
