Jerkoff Elbow 

A tennis elbow type condition caused by excessive, frantic masturbation while viewing porn or frantic, fast masturbation caused by lack of privacy (in dorm room, in men's room at work, etc). Once the condition sets in on one arm, the jerker often switches to the other, to rest the arm which is suffering.

The porn jerker thought that the ice pack might ease his jerkoff elbow pain.

Jetboat 

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."

Adjacent to Lot N (and often synonymous with it) at the Sports Complex in South Philly, the Jetro Lot is the location of a number of larger tailgates for events at the complex. These tailgates also tend to turn into some of the rowdiest at any event. In other words this lot is friggin sweet!

Normal Fan: Hey man, where you tailgatin before the Eagles game?

Crazed Fan: Jetro Lot!
