A person who will thoughtlessly jaywalk into approaching traffic.

A meanderthal is confident that any car speeding towards them will avoid them and that no driver has ever taken his or her eyes off the road for a second so it's totally safe to stop cars by throwing your body out in front of them.
Don't take Danforth Ave., the streets full of meanderthals.
