Micro-Urination
When one reaches their limit and can no longer last and has to urinate, but does not have the time to complete the job, so they drain off the minimal amount to allow them 15 more minutes of life before repeating the process again. This is often caused by standing in line for concert tickets, important business meetings, opening Christmas presents or talking to your best friend on the phone.
Dude, hold this ice-tea and don't lose our place in line to get the Kenny-G tickets, I have to take a Micro-Urination behind that police car.
