I ate too much spicy food and left a nasty present in our communual restroom
Eww. Why would you do that?
It's all part of my plan. I ate the spicy food to make the smell even worse.
That's a pretty gross thing to purposely do in a shared restroom. It's rude to make people deal with a mess or smell that you left for them. If you're not careful, you'll end up kicked out of your housing situation.
Whatever, I'm going to eat more food with lots of spice.
While you can't control some gastrointestinal issues, you need to flush and use some air spray or light a match, if possible. It's disrespectful to intentionally fail to flush the toilet afterwards.
