Reference to the infamous 426 Hemi Chrysler engine. Probably the greatest engine ever built. 425 Horsepower at 6000 RPM. This engine was found in the Plymouth Roadrunner, Dodge Charger, Coronet, Superbird, Barracuda, and others. Chrysler recently began re-releasing the Hemi. The problem is it isn't really a Hemi. And it could never compare to the 426. The 426 is the only real Hemi.

Old Mopar engines used in Dodge/Chrysler cars such as Chargers, Super Bee's, Road Runners, Challengers, and other muscle cars. The name was derived for Hemispherical cylinder heads using a SOHC design. The new "Hemi's" are not actually Hemi's, but just a copyrighted name used to sell cars. New Hemi engines are simply a waste of fuel, space, and money. Dodge achives it's power these day by low-tech cheap in-efficient engines. With Chevy you get about the same performance with about double the MPG. Dodge talks about their new Viper-powered V-10 Ram, which is the fastest stock pickup in the world. Well last time I checked, people don't by pickups to go fast, they buy them for hauling shit.

Dodge Sucks.
I am quite positive if Chevy or Ford wanted to make the fastest stock truck in the world, they could, without using a super-car engine.

Often pointed out on a car to distract attention from the actual shitty car itself.

Best person ever by far. Can treat a girl good, and is very special. Hemi can be non-talkative, and can make your life so much more amazing. And ladies, if you end up getting him, trust me he's worth it ;) don't let him go. Also, you mess with him, his best friend will beat you up ;) He can also, be a spicy and salty guy. :')
Best friend: "So hemi how's your day?"
Hemi: "It was fine, someone was messing with me tho-"
Best friend: "If I get accused for murder, bail me out."

A hemi is that fat kid in your gym class, every class/ school has a hemi. The hemi in your gym class probably smells somewhat like a dead horse. A hemi typically likes little boys, and sucks at life in general. Hemi's often make funny faces when attepting to do something. (This can range from breathing to playing softball) When this "hemi" makes one laugh, the hemi usually has enough time to toss an insult your way because of your extreme laughing. This is when you call him fat.
Hemi- Your stupid!

Aaron- AND TAKE A SHOWER!!
