5.7x28mm

A premier calibur invented by FN (Fabrique Nationale) for two of their premier firearms : the Five-seveN and P90.
It is compact, yet powerful like a rifle round (able to pierce armor).

5.7x28mm is also illegal for citizens to possess because of its armor-piercing capabilities.

5 year plan

When a college student goes to college without any hope of graduating. Student will typically go on 5 year plan when they feel they will not need a college degree to succeed in life or when then drop out of college then decide to go back. Even though they will not graduate, the student on the 5 year plan will still hold themself in high regard as they can make the claim that they have "some college" in their background opposed to only being a high school grad

Look at Greg, 22 years old and still only a sophomore. He must be on the 5 year plan... Wish I was on it

The phrase 'to dog out sb's five point oh' is used in the film 'Bully'.
