It's a "by invitation" group that mandates positive feedback. Here's the thing, I am a very positive person (hear that Fallsview?), but on matters of muscle, I fallback to GB bantz. I've been a member of this group for less than a day, and I've already had to backspace over replies of "YLLS", "would not hit" and "nice gyno".
Clearly, I won't last long here. I have a few getbiggers as "friends" (oh brother) on FB. Perhaps I should invite them and have some fun...
