faulty faucet
When a guy thinks that he is done peeing and puts his dick back in his underwear and a few more drops of pee come out, such as a faucet that when you turn off and drops still come out. This can be very uncomfortable for most guys because they have to continue their day feeling the pee on their skin.
John- "Damn it, my fucking faulty faucet is going to make me uncomfortable until lunch is over!"
