look up any word, like blumpkin:
A term used by engineers to allocate their hate for Sir Isaac Newton. If newton never lived our lives would be a lot easier. Because of that bastard we are forced to do work till 3am every night. A cross between screw and newton.

1 screwton = 3.569E^-5 (pa*Wb*m*V*kg)/(rad*s*ohm*mm Hg)^(e^ln(0))
"Man engineering sucks, screw newton"
