ButtCussion: Severe fall landing directly on
one's posterior axis, causing severe
pain to the point of nausea - as in a "concussion of the butt." Falling and landing directly on the gluteus maximus or worse, a direct blow to the coccyx, with
pain so severe that it causes concussion-like symptoms.
He jumped up into the
