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!!

Portland Steamboat

Inserting a candle (steamboat) into the anus and having vaginal sex, hence the "chugging".
