Poof guys
Guys that go "poof" out of nowhere. You meet them and they are amazing or so you think, and you really hit it off. They text you and maybe even call you. Then they just disappear off the face of the planet. Never to talk to you or see you again. No explanation. They are either douchebags, or they didn't get what they wanted, or they used you and are onto the next unsuspecting girl.
That guy never called me back! Everything was going great, then he was gone! he's one of those "poof guys."
