Cottonmouth? Rattler?
My friend made the weirdest noise from behind a boulder one time. I thought he was f'ing around with his dog, being a weirdo.
Evidently, a baby rattler knows the jedi-mindtrick, convincing my friend he was holding the baby rattler too tightly and was hurting it. Ya, snakes need to be held tight, and have very flexible spines.
$16,000 ER bill, paid by the Indigent Rattlesnake Bite fund. Not for indigent rattlesnakes, though I suspect the baby rattler was short on material wealth.
