Thought to have originated from the "
That 70's Show" quote "...is that a thing?".
Highschooler Joshua MacLatchie coined this phrase to mean you are absolutely sure that isn't even a real thing.
This also predates
Seinfeld because fuck physics.
Ex:
Zach: I totally
dunked my balls in her ass last night,
shit was so cash.
Shim-sham: That's not even a thing.
