Heli - V "derived from the term "helicopter". A "heli" is when a man is able to spin a woman who is on his penis fast enough to create enough downward force to provide lift, much like the propellers on a helicopter do. Also requires two other men be shooting semen away from the heli, as if providing fire support."

The equivalent of a "doughnut" in an AWD (All wheel drive) or four wheel drive car.

Because all four tires spin at the same time while doing a Heli, the entire vehicle rotates in a tight circle around it's near center of gravity, as opposed to only the rear rotating around the front of the car like in a regular, rear-wheel-drive doughnut.

Helis are easier to do than doughnuts, and usually result in tighter, faster rotation, but your car often has to have a lot more horsepower to break traction.
That Subaru pulled a sick Heli in the parking lot yesterday, it only took up two spaces.

A beautiful girl. She can balance looking good, after school activities, good grades, and an awesome personality all at the same time. She can be an amazing friend and super nice when she wants to be, and a real bitch to the people she hates. If you mess with her, she will be hard to gain her trust back. She has been though a lot and not many know her life story, but over the years gets stronger, prettier, and just better. She's really funny and so much fun to be around. You definitely want to be friends with her! She has many admirer, but she won't pick guys by their looks. Any boy should be lucky to have her.
"I wish I could be a Heli"
