You Understand Me?
A USMC drill instructor’s favorite phrase to add onto every single sentence. It is extremely annoying. Drill Instructors must be

Drill Instructor: “We are stepping off to chow in two minutes, you understand me? Don’t be the one that isn’t done making their rack by then, you understand me? I will slay you if you are fucked up in any way once you walk out that hatch, you understand me?!”
