When a male is having protected sex with a female and feels like he is screwing a bag instead of the interior of the vagina.
Guy A : Man, you ever feel like you're screwing a bag and you gotta put more work into the sex to get any pleasure
Guy B : Oh yes, its a Flop Out.
Guy B : Oh yes, its a Flop Out.
