this puts me in mind of a once overheard conversation: a slender woman mid-20s was chatting with a friend of hers both of whom had just had body fat percentages done with a group. The young woman was very upset because her body fat was very high for a woman indicating she was out of shape. She was upset because her weight was ideal for her height. She was even More upset because another woman - who in her words was "fat" - had much lower body fat and she just couldn't understand that because the other woman was "fat"!
I'm not even going to comment on your ManFriends comment - that's between the two of you but I do have to ask: if you're calling him your Man Friend - would the acronym be MF?

(SK's gonna nail me for that one! :-D)
