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
