A guy who is afraid to admit what he really wants and acts differently around certain people. If he's into you, you're his queen but once that's over he's a big douche. He doesn't like to admitting he likes you after it's well passed.
Beware: Tries to make you jealous with other girls, yet he's the sweetest and cutest thing in this planet.
My man is such a Diego.
Oh why couldn't he be more like Diego?
