Call me old fashioned (or maybe I'm taking the internets too seriously), but to say something like that to a man is probably okay. Expect repercussions or retaliation from it. Not that many on the streets could probably whup his arse.
To say that to a woman, especially one you don't know, is pretty low and aspersions should be cast because of it.
Also, the dudes line who laughed with him are just as guilty!
Any one who knows of it or him will remember that comment for a long time. It'll come back to him. He may never know why his pizza aways smells like urine or what ever but people will remember and he'll get what's coming right back around to him. I know I'd do every thing I could for him if I ever see "Rampage" on anything.
