Mach is the measurement according to the speed of light. In 2018, studies showed that 90% of teens learned the word from 'The Flash' and the other 9.7% learned it from the classic "Yo momma so fat her stomach grows at the rate of mach 4. The last .2% can't do math. The word is commonly used as a replacement from the term 'Light-o-meters' because the prhase upset the military task force in charge of greeting the Light side.
I" believe you can't even run a mach, Caitlyn." "Well sucks for you Barry she doesn't have super speed!"
