Chris was Bar Commando last night. He organized all 10 of us and had an amazing game plan for which bars we should hit in Philly.
A Facebook commando is a pathetic loser that hides behind his keyboard. They like to ban people from their pages when they post a differing opinion. They also routinely delete posts that do not coincide with their rants. Their rants are usually rude and and nonsensical; the types of things, that if they said them to your face, they would need plastic surgery.
