Sometimes they can be people who tell you how amazing you are, but still like to point out every single flaw and then add something like, "But I still love you" or "But you're still absolutely gorgeous!"
Someone socially retarded.
Also can be referred to as autogoober or a really obnoxious kid.
The most annoying about moonpies is when they say "I love you," especially if you say "I love you too" automatically.
Victim: Eh...moderately? I mean, I do so I don't get a gross unibrow or whatever.
Moonpie: Oh my god, they're so perfect. You're perfect. Oh...except those three hairs right there.
Moonpie: Can I hug you!?
Victim: I guess...
Moonpie: I love you!
Victim: I lo--Thank you.
Moonpie: I'm not annoying you, am I?
Victim (coughs): No. Why would you think that?
Moonpie: We should hang out sometime!
Victim: Uh, OK.
The act of going to a party of drunkeness, getting someone to pass out from drunkeness (amongst other things), pulling down ones (meaning yours) pants, taking a massive poo on their chest, ejaculating gooey substance on the poo, and lastly, taking another massive poo on the gooey substance of which is atop the mountainous poo-mountain below it.
As soon as this act of nastyness is complete, one (meaning you) would be best to completely dissapear from the party.
It was so nasty, I couldn't stop vomitting.
Kaitlyn always goes commando so I make sure to drop my pencil when she wears a short skirt, here's hoping for moon pie.
There's nothing better than a moon pie in the morning.
