John McCaining

To have a very conservative strategy when playing Super Smash Brothers in hopes to just be the last man standing while accomplishing nothing during gameplay.

This usually includes avoiding contact with other players altogether while occasionally throwing projectiles or using an item. A person who was John McCaining will usually end the match with a win and only one K.O.

Generally, this will cause everybody to detect that said player is John McCaining and then focus solely on knocking them off for several seconds, creating an adverse effect.

This practice can often be detected by hearing a flood of "come on, step it up" and "you're too slow."

"I can't believe I'm already down to one life, I think I'll be John McCaining the rest of this one out."
