Its the nap you have after consuming a bit too much beer. Your friends think you've just passed out but you are convinced you just dozed off cause you are a bit tired.
Check out Dan, he has passed out from way too much beer. Nah man, he is just having a beer nap, I had one last time we went out bro.
