Eye-hump 

To stare at someone in a creepy, sexual way, usually for several minutes without blinking or stopping when the person being eye-humped realizes he/she is being mentally undressed (and doesn't even want to think what else) by the eye-humper. If done right, very unnerving.

"Elmo likes to eye-hump you!"

three day hump 

The difficult period of the first three days of substaining from an addictive substance or habit. It is often the case that when you're trying to avoid doing something that you are addicted to, the earliest parts of it (often three days) are the hardest. The something addictive can smoking, drugs, alcohol, fast food or even a close and intense relationship. Once the inital peroid is up, however, the quitting, abstintence and rehabilitation process is more bearable on a day-by-day basis.

"Go easy on Mike today, he's quitting cigarettes. And he's still on the second day of the three day hump."

Jump Hump 

The next level up from the Mormon Dick Soak. A friend of the participating Mormons can jump on the bed to create a sort of artificial thrust, thereby increasing the stimulation of the soaking parties, while still keeping all involved in God's good graces.

Sorry I have to cancel dinner tonight, Stacy needs me to jump hump for her again.

reverse hump 

You hump, he/she/it antihumps in the opposide direction, resulting in a net loss of humpage.

Reverse humping: "I just picture you running around with your hips thrust forward, shooting a railing around like when you put opposing magnets next to eachother."

Ninja-hump 

When one comes up behind someone and clandestinely humps them for a short period of time, and disappears before the humpee knows what has happened... Like a ninja...

Oh my God! At the French Creek trip, Dijon Berlin came up behind Jane Smith while she was dancing and ninja-humped the shit out of her.
