The buff bod thing may not have struck the right cord in you because as an introvert you don't really like the whole "on display" kind of mentality that a comment like that implies. KWIM? You don't "get it" because it isn't something that you could picture saying about yourself. When you just don't really get something like that just reach down deep into your gut and bring up a little growl and say, "MMMMMMMMMMmmmmmmmmm Hhhhhhmmmmmmmmm, I'm sure you're right" or a tease, "We'll just see about that big boy".
