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.

This is a combination of a Cleveland Steamer and a Motorboat. It is when a man (or woman) excretes feces on a woman's breasts and then Motorboats her.

Steamboating is a sex act that involves farting into a plastic bag and then putting the fart-filled plastic bag over your partner's face to let them inhale your farts.
Kelly: Josh wants me to steamboat him. Should I?
Jenn: What's steamboating?
Kelly: Um it's kinda kinky... it's when you fart into a plastic bag and then let your partner smell it.
Jenn: Oh! Ben and I do it all the time! It really turns him on!
Kelly: Guess I should too then...
Jenn: You should! It's the best
