1. A song sung on someone's birthday.
2. The act of hitting someone with a container full of very hot tap water while they are sleeping or passed out; singing the happy birthday song.
My cousin was passed out on the couch so we filled up the dish basin with hot water and gave him a happy birthday, it was so funny!

When it's your 31st birthday, and you live on your own, with no wife, have a crappy job, no friends and no money, this is what you say to yourself in the mirror before bursting out into tears.
Happy birthday to me,
happy birthday to me,
happy birthday dear meeee,
happy birthday to... I suck! Waaaaaah!
