1.
A phrase commonly used by people from the future to indicate a problem with the Earth's gravitational pull. However, weight, supposedly, has "nothing to do with it." Phrase originated circa 1955 by a teenager in a life jacket.
"Whoa, this is heavy..."

"There's that word again! Heavy! Why are things so heavy in the future, is there a problem with the Earth's gravitational pull?"
