Having sexual intercourse with a woman while she is giving birth. This could or could not result in possible intercourse with the new born. It must take place after the woman's water has broken and should be celebrated as the first birthday present the baby receives.
"Dude, whats wrong with your baby's face?"
"Oh, after the Happy Birthday I gave her, her mouth might be a little off."
"The baptism was okay but I felt awkward being the godfather and the one to give her and her son a Happy Birthday."

When a man shits on a plate and smushes it up to look like a cake then jizz's on the top to make it look like icing. Then scrapes the 'cake' on his pubic area and makes a hole in the middle and sticks his cock in the hole. Then he makes someone eat the 'cake' and then suck his cock as a treat afterwards.
A: " John gave me a birthday cake last night, it was my favorite flavor."
b: " Really? Did you get his treat?"
A: "Yeah, it was awesome. Have you ever gotten birthday cake'd?"
b: "No, but it sounds yummy."

Similar to a destination wedding, it is a place picked by the birthday boy/girl that requires their guests to give up their week, their income and their lives...for the sole purpose of showering the Birthday boy/girl with inappropriate praise.
Hey Guys, I'm super excited for my birthday party today. I sure hope you can make it. It's a Destination Birthday in Honduras!!! I've checked Air Honduras and ticket prices are below $1500 roundtrip, please check the Birthday Registry.

A birthday kick is a tradition on IRC-Networks. Instead of claps on the butt you get a birthday kick. (birthday /kick)
