An act performed after human feces is frozen, as in a frozen stanley or a frozen francis. Two men then put opposing ends of the frozen turd in their rectums and proceed to "rock" back and forth, attempting to reach assgasm before the poopy melts.

Mike: Yea man, it looks like what we did last night with that frozen piece of shit.
Jacob: Yea, that was one sweet amish rocking chair.
