What does your heart smell like?

Vague hatred & disdain for humanity...that's what my heart smells like. Since you're on here, your heart probably smells like a profound desire to touch alter boys.

They smell kind of metallic and waste like.

Copper?

Iron, oxygen, waste, and blood cells.

this isn't the place to ask (Google is free) so I'm gonna not tell you my experience with dissecting a pig's heart in a high school lab just out of spite. good luck.

Like blood

Thought this was a deep metaphorical question-

Mine? Probably chocolate.

Blood and internal organs. Gross

Go to a morgue and smell for yourself. It depends on the stage of decaying it is in. Putrefied bodies smell worse than a landfill where all the garbage are collected and dumped. The organs decay and give out foul smelling liquids and gases, heart inclusive. And real intestine smells far worse than farts. Just buy some pig organs from the butcher shop (pigs give the closest smell to humans) and do not put them in a freezer, keep them in a warm locked room for a week, open the door after the week and smell it, goodluck.

Probably pretty bad. Internal organs probably smell really gross.
