i turned into she-hulk again today

this morning some maybe 15 or 16 year old kid came from behind me and smacked my ass. but wasn't like just a smack but like a gigantic wallop and grab. i jumped and screamed.he had to have been planning it because it packed some momentum. by the time i spun around which took a second because i was in such shock, he pretended he didn't do it despite there were no other people around at all and then he ran. when i spun around and turned into the she hulk and yelled "WHAT THE FUCK?!" i actually saw the look of true fear in him so that bit was nice. this happened directly in front of my job.
