I feel a bubble coming on
My butt is about to let out a monster fart.
I was in the middle of a podcast and felt a bubble coming on, so I just said 'sorry' and walked out.
I was trying to be cool at the party, but then my butt let out a monster fart and everyone laughed at me.
I told my friend I was going to the store, but I was really just running away from a bubble.
