This definition is only directed towards young men, it is not meant to be offensive to girls: "creeper" is a term typically used by young women, usually young women who like to party, which means "I am afraid of you because you are by yourself", or, "I am afraid of you because you are not socializing." I've noticed that women tend to label men creepers if they have dark features, such as thick eyebrows or a distinctively superior look. Something else I've noticed is that older, more mature, and usually brunette women are actually ATTRACTED to these types of men. Think about it, young men who have dark features, are independent, and mysterious, seriously, I guarantee you will win the love of a beautiful women, and dont even worry about being labeled a creeper, you will learn later that it's a compliment.
Being a creeper may be when you're at a party where you feel like you don't fit in with the girls there, and not wanting to talk to them so you just chill by yourself or with your guy friends.
A person who does weird things, like stares at you while you sleep, or looks at you for hours through a window. usually a close friend or relative. you know right away if that person is a creeper or does creeper things. it is not hard to spot the creeper.
A type of creature often seen in the In Development game, Minecraft. Similar to a suicide bomber but this creature lures prey into its line of fire by frowning and looking generaly sad. People fooled by this act soon are blow to millions of tiny bits as the creeper explodes. The creeper earned its name for its ability to swiftly sneak up on an unsuspecting player and quickly kill them, destroy their construction, and leave them exposed to more powerful monsters.
