Gorilla sitting — or, gorilla sittin’ — refers to when one or multiple sexual partners is/are engaging in intercourse while straddling the corner edge of a bed or other similar piece of furniture, back arched sitting forward on their knees and fists, fists clenched the same way a gorilla would articulate as it sits in its native lowlands.
Yeah, no, he was so hot … he brought me to his bed and had me clothes-off gorilla sitting within the first ten minutes I was there.”

Or

“There I was, ass up on the edge of their bed at attention on my knees and first knuckles … they had me gorilla sittin’.”
