Jabroni 

In wrestling: a jobber.
In reality: Dumbass. Loser. A no good son of bitch. Talks a lot of shit but can never back it up.

Calvin: Do wanna pick up some McDonald’s?
Kiff: Sure
*gets to McDonald’s*
Calvin: Dude I forgot my wallet, can you pay for me?
Kiff: you’re a fucking jabroni

Jabroni 

A loser, poser, lame-ass.

One who talks the talk, but could never walk the walk.

One who talks shit and doesn't back it up, but rather ends up eating their shit in return.

A fuckin 'tard.

Bill: "Hey Bob, you're a big pussy!"
Bob: "oh yeah, well..(breaks Bill's face in half)...who's the fuckin' pussy now you fuckin Jabroni?!"

Damn Jabroni's, I'm always breaking my foot off in their asses!

jabroni 

A slang term in professional wrestling first used by the Iron Sheik and then again later by Dwayne "The Rock" Johnson. It is derived from the word jobber, which is someone who routinely loses, or "does the job".

The Rock says, "Know your role and shut your mouth, jabroni!"

Jabroni 

Pronounced: Jah-bro-nee
Plural: Jabronis
Pronounced: Jah-bro-nee-ss

Definition:
Jabroni is - to me and maybe some others - is a one-size-fits-all insult. Jabroni can be used to insult anyone for anything. They could be a poser, a lame-ass, a d*ck, an asshole, a motherf*cker, really anything.{1} The pluses to using jabroni over more traditional insults such as the ones listed previously are that it's not used often - giving an enriched and more important and potent insult{2} - and that you can use it for anything as said before. If you're teacher is being just a c*nt, call them a jabroni. He/She will not know what that means, and you can tell them it's a positive thing. Meanwhile everyone else knows that someone just straight-up called them a(n) *INSERT INSULT HERE*.{3}

Origin:
The word jabroni is a new-age insult. It's a new word; we've seen it be created. Origin shows usage from WWE wrestling. Where "The Rock" uses jabroni to describe a "jobber". How some discovered it in the form shown here was from the Vinesauce live streams. The song "The End?" by "The Four Jabronis" is linked here.

{1} "Kyle is such a jabroni."
{2} James: "Hey Donald, you're a f*cking dick."
Donald: "Well James, you're a jabroni!"
James: "Uhh..."
{3} Mr. I. C. Weenur: "Alright ya little s*its, you have to do homework over Spring Break. Read chapter 69 then make a 2 page summary with at least 2,000 words."
Ben: "Mr. Weenur, you're a serious jabroni."
Mr. I. C. Weenur: "What's that?!"
Ben: "A good teacher..."
Mr. I. C. Weenur: "Okay."

Jabroni 

Used by Mac in Always Sunny. Badass word. A piece of shit. A loose end. And a complete moron.

Mac: We're like a couple jabronis here without skates on.
Charlie: Bro, you keep using this word "jabroni" and it's AWESOME.

Jabroni 

An asshole. As in: “Look at this fucking asshole!”
Like, if you see someone riding down the middle of the street on a unicycle, naturally you’ll say “look at this fucking asshole.” That’s how you know, the fate feared by all, one worse than skinny ankles, that they’re a fucking jabroni.

“What’re you doing jabroni?”
“Look at this jabroni pouring his milk before the cereal”
“Yo jabroni stop being a hoe”
...and renditions thereof

Jabroni 

A punk/idiot. Someone who you try to avoid. Someone with no redeeming qualities.
