sempla-fi means: While I do love all our Marines and their work, this Marine is my favorite. One who requires explanations for every aspect of any situation. One who enlists in the USMC as his sole identity and value. You have to stop the drunk man at the bar and take 45 minutes explaining why he cannot kill people because they find him funny. K.I.S.S is the one preaching simplicity stupid. This is the guy who hasn’t been in the USMC for over twenty years, but still claims to be “once a Marine”, “Former Marine”, or “once a Marine”. One who is demanding perfection, but far from it. (in Community Dictionary, added by Javier Compton)
