Dutch Steamboat 

During anal sex:

shouts right-wing propaganda
despite libertarian values

(Reverse Dutch Steamboat:
shouts left-wing propaganda
despite wingnut values)

In an open letter, the girlfriends of more than 40 priests have called for a relaxation of the church's stance on celibacy to allow a limited range of sexual practices, including the reverse Dutch Steamboat, the Stockholm Slip'n'Slide and the Sorcerer's Apprentice.

British steamboat 

When one person giving oral sex to a male recipient drinks hot tea, thus burning the penis of said recipient.

Sean was giving me a British steamboat and I ended up in the hospital for 3 days. Totally worth it!!!

Ol' Mississippi Steamboat 

Drop a sweet loaf onto your partner's back or chest. The bigger the better, but it's gotta be clean and in one piece. If you want, you can use a toothpick to make it look like a steamboat, and then you can attach a flag to the toothpick and fly it on loaf. For some reason, I like the hammer and sickel, but you can put whatever you want on it.

Then, sit on your partner's face and urinate towards the steamboat. This will mimic the action of an Ol' Mississippi Steamboat.

ENJOY!

This freak I was getting with wanted me to float my Ol' Mississippi Steamboat on her boobs.

Steamboat 

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.

After eating Chipotle for dinner I had such bad gas I gave my girlfriend the steamboat last night.

Steamboat 

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.
