similar to drunk dialing or drunk texting, it's when you are drunk and add items to your netflix queue. you don't realize you added the items until you receive a dvd in the mail that you have no memory of requesting.
you go to the mailbox and open your red envelope ready to watch the next episode of "it's always sunny in philadelphia", only to find that you have "marley and me" instead. and you're like WTF! how did this shit get in my queue?! i must have been drunk netflixing last week.
