When a guy is fingering a girl's asshole and he puts that finger in his mouth and gags himself until he throws up onto her asshole and then the girl lets out a fart, making a barf bubble, and after it pops, it shows the location of her asshole and then the guy fucks her asshole. HAPPY BIRTHDAY!
"Hey did you hear?"

"Ew man, that's fucking gross."
"Yea but I heard it's like getting high."
"What ever man, that's fucked up!"

Anyways, if you are looking for the definition. It's self explanatory (The opposite of happy birthday, used as an insult when it is someone's birthday).
