A DC Comics superhero with the ability to run at impossible speeds from sound to light. There have been lots guys to wear the costume in the past(Jay Garrick-Barry Allen)But the coolest one so far is Wally West who started off as the original Flash's sidekick. One thing about the Flash is that he makes a lot of F'ing enemies, so he famous for his Rogues Gallery.

To immediately, uncontrollably projectile vomit when exposed to a scenario so revolting that one's innards rush for the proverbial Fire Exit, i.e one's mouth.
When he saw the Hamburger Lady: no arms, no legs, remaining torso and head with 4th degree burns, though a trained trauma physician, he flashed on the floor, sending vomit bouncing back up to the bed on which her moaning body lay.
