Pretty sure they would eat you out of rage and envy. Unless you kept your wits about you, they would slowly encircle you, leaving you with nowhere to go because every direction would lead into a mountain of lard three feet thick. You couldn't climb out, because the lard has no rigidity, and your foot would sink in, further entrapping you. And the grease excreted from their hides would make it impossible to find any traction. They would then close ranks, suffocate you with their massive girth, and consume you. Well, one of them would, anyway. They'd just unhinge their jaw and cram you down their rancid gullet. If anyone does this, make sure they're within sight of an exit at all times. Suffocated by butterhogs is no way to go.
