I have been told this. Its an easy thing to understand, I dont see how your so baffled by it. Compared to other people your height and weight apparently you heald your ground well. I wear baggy clothes, I slowtch and really dont act tough. But I can raise some hell when it comes to weights or fighting. People dont expect it because I dont look 6ft 175lbs. I come off as 5'9 150lbs probobly. But when it comes down to it people get kinda like where the hell did that strength come from. I think you feel as if he is hitting on you. Well say it back and see what he does. Who knows, Maybe he will buy you a slice of pizza. HA! Homophobia to the max.
