The Nep (or Nepotism) is a sexually transmitted disease that causes spontaneous pregnancy and a rash with the face of a really hot teenager on it. It is mostly spread by scissoring. Other forms of the nep have been found but are unknown as to how they originate. (Most suspect that it is probably spread through a girl named gwen. She IS the nep.)
"Whoa man! Step away! It looks like you have a nasty case of the nep! ...although that rash is pretty sexy."
