어도 죽다

you'd die even if…

A concessive "-아/어도" (even if) plus 죽다 "die", saying death follows regardless: you'll die even if you just say the name Bangle, it dies even if it only eats a little, a creature that dies just from breathing. Half the lines are hyperbole or fiction rather than literal — Superman doesn't die even if he falls, raising three siblings alone would kill you. Note also that casual Korean uses 죽다 for "be finished, be wiped out", which is what the short-selling line means.

Register: casual, often hyperbolic
