look up any word, like b4nny:
 
1.
PKW
An acronym for Phone, Keys, Wallet: the 3 basic requirements necessary for any activity that involves leaving the sanctity of your own home.
After a grueling walk to the club in a drunken stupor, it was to our group's misfortune that i had left the most crucial part of PKW back at my house: my wallet.

PKW
One major prick. The kind of person that just makes you want to scream shut up you giant loser bastard and then punch them in the face.
That guy is a major PKW
