hell yeah brother

Slang used by U.S. Armed forces after a successful or positive occurnace.

USA Slang used sarcastically by Americans and Foreigners alike to express sarcasm towards affairs that are usually seen as republican or conservative in a radical fasion. Such as guns, women, and the freedom of speech. Often used by the youth to middle-aged men when agreeing to hot-takes in a ironic way but not really agreeing to the ideals of it.

Mainly used as "edgy humor" that boomers may not understand, since it is now part of internet culture. This is stereotypical American Hill-billy self-degradation.

And it's funny!
