Backyard steamboat

While wearing a turtleneck shirt/sweater that is tucked into your pants, you fart. The gas then travels up the shirt/sweater and out the turtleneck.

Did your face just shit itself, or did you backyard steamboat?

Steamboat Willie

While in bed receiving fellatio, placing the covers over your partners head, yelling "toot toot" and giving them a dutch oven.

When I want Veronica to really gag on my cock, I give her the old Steamboat Willie!

Steamboat Jimbo

One that mounts another one's chest and squats in the manor of shitting on said chest, before preforming sexual intercourse....

The female version of this would be called Shitty Taa Taa's where man uses the shit from his chest as a personal lubricant for titty fucking the female and finishing with the female giving him a blow job.

Hey babe, "Can I get a Steamboat Jimbo?" This can only be used by someone that already knows what a Steamboat Jimbo is... If not you can refer to the definition above!!
