faux-cliche

A saying that appears to be a cliche but has probably never been said before or has no actual right being a cliche

Transcendence: How was selling tacos at Paco's Taco Stand?
Parkman47: I made as much that was as a dead man makes selling dirt
Transcendence: You know, hombre, that's a fucked up cliche
Parkman47: Yea, I just made it up, it's a total faux-cliche
