Doing something you haven't really got time for, usually before going out. Origins from comedy series 'Police Squad' where the teller completes his chores after being fatally shot.
When five guys wearing sunglasses fuck a single girl, preferably one in a nurse outfit, all pull out and ejaculate onto her back at the same time, while shouting: "Squirtle Squirt!".
During intercourse when a male both ejaculates and rips ass at the same time. Truly one of the bestfeelings of all time although it may lead to you being single.
