A facetious false etymology for the rank "PFC" (private first class, E-2) in the US Marine Corps. Since PFCs are often tasked with menial work like mopping, sweeping, and picking up litter, this term is used either to mock them, or by PFCs themselves to lament their low status.
A: Dammit, Sgt Fuentes has us out police-calling cigarette butts all morning yet-a-fucking-gain. Why does this shit keep happening to us?
B: Well, we're E-2s, and you know what PFC stands for: "perfect for cleaning".
