Get These Balls

This phrase was first made popular by LL Cool J when interviewed on the Jason Ellis show on Satellite Radio. LL Cool J constantly repeated the phrase "Get These Balls" during the interview primarily as a rebuttal since he didn’t understand Ellis’ humor and felt threatened.

1. (idiom) To get something started

2. Get it started with your partner

Originating from a dumbshit comment posted by stupid fucking Clyde on the Facebook page "DADoEM", "Getting the ball rolling" is the action of liking your own status/comment in order to take advantage of the natural, learned psycological reaction of avid social media users to "like" a post if there are already existing likes present.

A response to someone who says something that indicates that they are lacking in self esteem.

To get up the courage to do something U R scared to do.

To overcome your fear, to act despite your fright and show some confidence by being a man.

The phrase "to get your balls out" means to pluck up the courage to do something. This can be anything, from riding a ferris wheel, to jumping off a tall building.
It is based on the theory every one has the courage or "balls" to do something, it is just a case of "getting them out"
