I first got dunked on in 10th grade. I was doing the 3on3 NBA Hoop It Up tournament in Springfield MA and some inner city kid crossed our "PG", my friend failed miserably at a back tap steal attempt and he straight shit on my then 6'4" skinny ass.
I only got dunked on once in college ball. We were playing against a NCAA Division 2 team and they had this huge 7 footer. On my first trip guarding him he drop stepped and dunked it before I even knew he jumped. Next trip down I side stepped him and stripped him as he went up.....def wasn't fun.
Due to the tallness, I've had some nice dunks on people too.
The first one I actually have on video and cherish....so for the 4th or 5th time, watch it dammit.
The 2nd time was a few weeks later in a 5on5 game with friends. Buddy tried a hook shot from one post, air balled it over the rim, I went up with 2 hands and tea bagged his defender.
I never dunked on someone in a high school or college game.....but when I was playing last summer with Kathryn's brothers I threw down an alleyoop over her brother's friend and cut his lip with my knee. Vicious
Yay for tall people
