A person who is EXTREMELY outgoing and talkactive to everyone. The person often loves to party, shop, get drunk and use drugs. They hate not-so-outgoing people and they love to talk about "daily basis" things in life. They speak loudly about their dreams (often being a stripper, etc.) and in the end, they never achieve any of those.
Brittany (Blonde bimbo): "Ooh, we will have a BIG party this weekend, with 9000 guests! OMG! I'm gonna get drunk and dance on the tables!"
Brittany is a stereotypical reality whore.
