The Brown Birthday Suit 

The Brown Birthday Suit - On your birthday, your partner holds a lit birthday candle in their mouth. You sing happy birthday to yourself (because there's a candle in your partner's mouth). After finishing your birthday song, you blow out the candle with a forceful diarrhea spray. Usually, it happens at the height of the birthday celebration.

My mom wanted to give me the brown birthday suit, but I got her to give it to my dad instead.

The Birthday Suite 

A fabled spa/resort somewhere in the USA where, on your birthday, you get to relax for the whole day. You don’t wear any clothes from the time you enter to the time you leave, and you get to spend all day having sex with multiple partners and feasting on Little Debbie snack cakes.

Where the hell is Tim?

Oh, he’s over at the Birthday Suite. He’s turning 41 today.
