That fart which gives you that extra little boost to get the last bit of pee out. (The emphasis on ending the piss.)
Unloading my bladder, I tooted near the end of my piss to give some extra power and get the full amount out, you know, gave it that emphapiss. Just that little bit of emphasis on finishing the pee brought on by the power of a fart.
