Peahead (n.): A fucking annoying preteen slutfaced bitch who thinks she is friends with everyone everytime she sits on their lap like a dog, or forces them against their will to take a picture with her for facebook tags when REALLY they just want her to get a life, go back to middleschool and leave them alone. One who is extremely annoying, loud, distruptive, destructive and who cries a lot. similar to a child.
One who is also not very bright.
Used in a sentence:
ex. Wow, Alix Underhill is such a fucking peahead that everytime she shows up unwanted at an older party and pushes her tiny little prepubescent mosquito bite breasts together in an attempt to blend in with the older crowd, her tiny little peahead just barely pokes over them.
ex. I fucking want to squish peahead all the way back to 1993
