Feat of gravity
Continuing my sexist ways, I leer at the woman’s cleavage while calling it a “feat of gravity.” What the object does (defying gravity) swaps in for the object itself (pair of breasts). That's a metonymy. By the way: I am not literally a sexist, but do sexism for the sake of my art. The assumption of a sexist role qualifies as—you guessed it—another trope: irony. Two tropes in one! What a pair!
