Fons
Someone who is amazing, fun to talk to, a smooth talker, smart, sexy, attractive, has good hair, can be a player, flirts too much, and can make any girl fall for him. When he's drunk he's hysterical and wild.
Clever, smarter, good person, a person who's called Fon will be a great friend.
Also is a name who inspires confidence and Pokemon/Kingdom Hearts adiction.
