armchair gladiator
An armchair Gladiator is someone that watches UFC and never misses an event telling you exactly two seconds after a move was made what move the guy was going to make. He's never had any martial arts training but can't tell you all the moves that it takes to beat certain opponents because he plays Street Fighter video games.
Watching UFC with Todd is so freaking annoying he's the worst "Armchair Gladiator" and hasn't been in a fight in his life!
