Sometimes

metaphors get very consequently drawn to a conclusion and then might become too real to bear.

Yet I like this weird stuff.

Like here where the lover is likened to a "dear little piranha" who is told to tear up the singer. Not just this, but the piranha is envisioned as drinking his blood and breaking his heart, that is beating just for this lover.



The effect is that this sterotyped metaphor of a broken heart is given new power, fresh meaning.

Similarly here : "You! You break my heart. You tear me up in so many parts. One part for you and one for me and that is how it ought to be."
