Fart cake
In the early days of relationships, we’re all on our best behavior. We dress up nicely to go out for dinner, we always open the door for our partner to walk through first, we laugh at terrible jokes, and we make polite conversation with work colleagues and weird extended family.

We also never fart in front of each other. As time goes on you become more relaxed around your partner, the more confident you get in your relationship. You might even burp during a meal, or after a beer. Don’t fart in front of this guy, though, or you’ll get a cake celebrating the first time it happened, and have to explain that to your coworkers.
