A phrase used to accuse someone of staring at you, often used by Drill Instructors at Marine boot-camp. The point being that if someone does't have a valid reason to stare at you (like you owing them money) then they should stop doing it.
DI: (notices recruit looking at him) Hey recruit, do I owe you money?
Recruit: ... what? Sir, no sir!
DI: They stop frickin' eyeballing me then.
Recruit: ... what? Sir, no sir!
