Sam is the name of one who constantly faps to My Little Pony, and lies about him liking hentai. He also makes plenty of VERY dirty jokes when he feel awkward. In other words, Sam is a very dirty person, who tries to fit in to the group, even though he lies about being dirty all the time.
A Sam (male) is someone kind, sweet, sensitive, and caring. Sams are great loyal friends that you just can't get enough of- you would follow them anywhere. A Sam has incredibly soft hair (for some reason) good looks, and a Sam will always make you laugh even at your lows. Sams are very smart but they often are very modest and don't give themselves enough credit for how great they really are.
