someone, normally a girl, who is too happy and exaggerates how happy they are that it gets to the point you want to slap them in the face. Also means they are slightly passive aggressive, bitchy, very sarcastic, tries to act cool and lies all the time to protect themselves and gets the other person into trouble.
"Oh my god, she is so annoying and prepy, I want to slap her in the face."
