bigmaktruck's definitions
A person involved in a friends with benefits type relationship who is asked to be their valentine. Since neither parties are dating, they are then each other’s sextine during Valentine’s Day.
“Omg. He asked me to be his valentine even though we aren’t in a relationship, we’re just having casual sex. I guess I’m his sextine!”
