look up any word, like tribbing:
 
1.
The act of farting on a Woman's breasts. Similar to a "motorboat" but with with added power and control. This act can be performed in a variety of settings but is best while both parties are crouched in a bathtub and wearing Captain's hats.

This act is usually followed by shame and uncomfortable eye contact. Jetboating is not recommended before family functions or important job interviews.
"Hey Zeke, I could really go for a Jetboat right about now"
"Oh yeah? I'll start the bath if you want to grab the Captain's hats"
"Wait! Tomorrow's Thanksgiving, maybe we shouldn't."
