When a female is at the specific height were she can perform oral sex on you without having to get on her knees or squat down while both of you are standing.

A girl who is a great artist, and friend. Her short height is where her nickname comes from. One of my good friends.
Guy#1: wow, who drew that? It's amazing!
Guy#2: Fun-size did.
Guy#1: all right everyone, time to come up with nicknames.
Guy#2: she's short, she should be Fun-size.

Having a penis that is in the small category. All though it is called "fun" sized it is not something to be proud of because the fun does not refer to the intercourse it is a joke on the fun size candy bars. DO NOT TELL SOMEONE YOU HAVE A FUN-SIZED PENIS.
I was at a party with zack and we got intimate, i was turned off because his penis was only a fun size
