"Hear me out" is a popular phrase that seemingly originated on Sept. 25, 2008, via Twitter, according to Know Your Meme. It's a phrase that someone might use when they have something absolutely bonkers to say and feel the need to argue their viewpoint.

For example, someone might say "Hear me out" if they have a crush on someone unusual and want to explain why they like this person to their friends. Or if they work at a company and have an unprecedented idea to present to their team.

Basically, if someone uses the phrase "hear me out," they should have a compelling argument ready because what they're about to say is clearly ludicrous and needs an explanation. They should be saying something controversial. Something absolutely wacky!
