Following Newton's law of every action has an equal reaction, The Newton describes the event that occurs when one is able to take a dump while ejaculating at the exact same time. This has to be done at the exact same time or it is not The Newton.
"So I got bored and decided to try The Newton...I failed."
Also referred to as 'newting'. It is where you do a headstand where ever you are, or in any place you can think of. Named after Isaac Newton, for when you are 'newting' you are defying gravity with your feet in the air. Look at is upside-down and you'll be holding onto the earth for dear life as to not fall into the sky.
