bum birth

The act of finally following through in the comfort of your bathroom following a long period of constipation. The feeling of joy mixed with a likely feeling of discomfort due to the build up of matter since the onset of constipation creates the strained feeling of childbirth from the rear. Usually followed by a feeling of weary elation that is once again similar to that feeling following the birth of ones child.

'I finally gave bumbirth today.'

seventeenth birthday

The time when a boy/girl turns 17 and grows a tail.

"hey Martha, did you see the tail on that guy?"
"oh yeh, he is hot! Did I tell you I was at his seventeenth birthday?".
"Tail is a euphemism btw".

October 13 birthday

Most likely an emo or homosexual with dyed hair, generally not the best friend cause they’ll ghost you or be genuinely dry, but with people they care about they could be a walking celebration, doesn’t know how to start a conversation but when they’re in one they’re either the funnest thing ever or the most boring thing ever (no in-between) they’re also most likely a geek but they’re a cool awesome person but hard to become good friends with.

Regular friend: I heard she has a October 13 birthday, she’s cool but they’re kinda boring
Good friend: what do you mean? They’re a walking party!

Happy Birthday

The act of performing a celebratory ejaculation on to your partners chest , followed by a quick reversal to release a confetti filled fart on your partners now cum filled chest.

Man Billy surprised me with one hell of a Happy Birthday last night, I am still wiping confetti of my tits.
