party like it's 1999 

to party like there's no tomorrow. Live like today's your last. In the 1983 Prince hit "1999" he refers to "2000-0-0 party over, oops - out ot time" so tonight he "parties like it's 1999". This became a catch phrase in the American lexicon.

After the Pink Floyd concert we walked over to the campus strip, hit the bars and restaurants, drank like fish and generally we decided to party like it's 1999.

Party Like A Millionaire 

A song by the dirty, electropop "scene" band Millionaires. It is labeled explicit by itunes and is controversial. It's very catchy and the music video is very racy. It is the first song after Dani Gore left the band.

I do what I want middle finger in the air Gonna party party party like a millionaire. Gonna dance like a slut, and I don't even care Gonna party party party, like a millionaire. Millionaire, like a millionaire. Tonight I'm gonna party like a millionaire

Lyrics from the chorus of the song

Party like a werewolf 

When one wakes up covered in food and surrounded by wrappers with no recollection of the even happening

Dude 1 "dude you made a mess"
Dude 2 "fuck man, I partied like a werewolf last night"
Dude 3 "awesome man I party like a werewolf every night"

Party Like It's 1999 

A verb meaning to party like you believe it's the end of an era; similar to the way people partied on New Years in '99 because they thought there would be a massive computer crash.

For New Years 2012 I'm gonna party like it's 1999.
