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."

The sound one makes by placing his or her face in cleavage and shaking their face back and forth while exhaling creating a "brrrrrrp rrrrp rrrrp rrrrp" sound.

The hummer she gave me was so good, I gave her a speedboat as my way of saying thanks.
