Anyone who wears a medium should refrain from being an Internet tough guy.
This logic is faulty for numerous reasons.
1. Generally juice head guys like to wear shirts that are a size or two too small. So even though this guy ordered a medium he could conceivably be ripped.
2. Manny Pacquiao, Floyd Mayweather, Arturo Gatti, Mickey Ward, etc would all swim in a medium t shirt and Dave does not want any piece of them.
3. Having met a bunch of posters a few years back at the BEB get together I can truthfully say most of them needed xtra large t shirts and none of them were the least bit intimidating. Well KOB is a big dude and Marillac may have done a cycle at some point in his life but other than that a big shirt does not a tough guy make.
4. You are being sexist. Could be a big girl for all we know.
5.. Finally, I like Dave but he is not exactly built like the Ultimate Warrior himself so I think he should just send this little guy/ Big Girl his/her shirt before he/her tracks him down.lol
