A person who dresses like an animal with the intentions of partying harder than the average person. One who organizes other party animals, because we party animals prefer to travel in groups; adding to the chaos and go-off factor. This person doesn't necessarily always need to dress like an animal to party, but facepaint and neon colors are highly encouraged. And most importantly, a party animal has more fun than a regular person could ever fathom.
Look at that awesome guy in the neon leopard leggings and amazing facepaint, he is having so much more fun than me! He must be a party animal!!
Anybody who after hearing any song by LMFAO thinks that they party hard, love "techno", or can "shuffle". This trend is typical among frat guys but is also very common in any other type of douchebag.
Guy 1: "Tonight I MAY get locked up for mass murdering some party rockers..."
Guy 2: "Stop with the party rockers. That sounds faggish"
Was once a pejorative term for dark socks or dress socks. This was back when pretty much everyone wore white socks and wearing dark socks was not cool. However, this has changed so maybe the meaning of the word has flip-flopped.
Nice party socks, dork.
All my white socks were dirty so I had to wear party socks.
