the dirty rob Gronkowski is an activity to do during sex, it when she is bent over with her fist on the bed and legs up straight while he hits it from behind. he calls out hike and she shits in his hand and he tries to get as much of it as he can after he has collected the shit he Yells "GRONK" while spiking the glob of shit on the back of her head like rob in the end zone.
