no shit lol
iv done crazy shit like that to people
i have this thing called a "hump walk" and and onetime we were walking behind an old couple and i get behind the old woman (my friend was there) and i start humping within centimeters from her rear end as we walk along
also a homeless guy onceu bent over at nighttime in a sidewalk to lay out his newspapers so he could sleep there, and i get behind him and start doing the same thing, (pelvic thrusting right behind his ass- cuz he was bent over it was funny)
