Speed Goat 

Slang name for the North American Pronghorn (Antilocapra americana). So named due to it's close resemblance to a goat and it's incredible speed.

While it's difficult to measure their speed, most sources state upwards of 70 Km/h, and they're known to be the second fastest land animal, second only to the cheetah, but able to sustain higher speeds for longer distances than the cheetah.

Oh, Crap! We're going to hit that speed goat. Duck! Why do they hang out near the highway?

I've given up hunting speed goats because they taste like a cross between a Slim Jim and sagebrush.

Any animal that willingly and suicidally places itself between your automobile and your destination at an inopportune moment. From the combination of Speed Bump + Goat (generic animal).

Watch out for those Speed Goats in the middle of Wyoming, they'll get you every time.

Sebago Speedboat 

n, v. The act when one man buries his face in between another man's buttocks and vigorously throws his head back and forth while resonating his lips to make a "brrrrr" sound. Very similar to motorboating.

I almost passed out with delight when Henry knelt behind me, buried his face between my naked ass cheeks, and gave me a Sebago Speedboat.

Mexican Speedboat 

A car so filled with Mexicans that the rear of the car hangs low to the ground giving it the impression of a speedboat speeding across the water.

"Hey did you see that Mexican Speedboat? I think the muffler was sparking."
