While suffering from acute flatulence, stick your ass in a girls breasts and fart. Related to the motorboat. Not to be confused with the hot carl or the cleveland steamer.

When you are wearing a turtleneck sweater and you fart, the fart gasses will travel up your pants, up your sweater, and exit through the turtle-neck opening at the top of your shirt. The turtle neck acts similar to a funnel on a steamboat (aka steamship, steamer).
After finishing a two-pound burrito and leaving the restaurant in his turtleneck, Javier was farting so much he resembled a paddle steamboat traveling down the Mississippi.

The act of taking a hit of weed then going under water and blowing out all the smoke. The bubbles will then pop at the surface of the water and smoke will come out resembeling a steamboat.
