Princess Bitchface
When someone, a girl or guy, gets offended with another and then makes a huge issue out of it and tells everyone except the person who they're angry/upset with. This syndrome can last for months at a time and is usually followed by some narcissistic excuse for the drama and a proverbial eulogy of a conversation dealing with the relationship between the two parties.
"OMFG kayleigh said all that about me?!! When and why?

"Well, she's mad about that thing you did last summer."

"ITS MOTHER FUCKING MAY NOW! WHY DIDNT SHE JUST TALK TO ME?"

"idk man. She's just being princess bitchface about it."
