A WARNING TO ALL GUYS WHO ANSWER THIS QUESTION!
Whenever a girl asks this to you...you are WRONG no matter what you say!
Some responses to questions just start out in negative points!
I would say weight means nothing, its the amount of muscle you have. I'm 210, but have a 33" waist, but if I go according to a scale or weight chart, I'm overweight. By their standards I (5"11") should only be between 155 and 175, and when i was 175, i looked anorexic, so, its all about the TYPE of weight you carry, not how much. But, I've never seen that many 350 pound guys who are healthy, so there are reasonable limits I guess.
