And to me this is used to deflect a lot from a lot of problems. It's utterly ridiculous at times.
Gangers breaking your face in, in the open, and for no reason? "Break THEIR faces in."
Friend ICly gone AFK several times, and it irritates you OOCly. "Rob em blind and break their face in."
Solo got you deaded, "Break their face in."
Someone targeting you with rumors and false accusations, harassment, etc, "Just break their faces in."
It's in denial of a lot of realities to the situation. namely that your character doesn't have to be a combat monkey. You might not have the capabilities or the contacts to oppose this character. And that's for good reason. Encouraging the break their face in type of play is ultimately, a futility, as it is basically encouraging at times players to act utterly out of character. And while it is funny from a memetic sense... It can confuse new players.
A better response might be, instead, "Look at your tools, and plot against them."
Because "Break their face in," implies that everyone should be skilled at combat. And is reductionist to the extreme. And makes the reality of the complex political interplays at center stage and at the periphery of the game, seem much less important than the smash and grab moment to moment lifestyle.
Just my thoughts, TL:dr, OOCly advising people to break their enemies face in, is reductionist and denies the reality of the situation.
