Normally done whilst buggering a young lady (typically one who rides side-saddle).
The young lady ingests a piece of ham or bacon tied to a fine thread, which the man holds whilst buggering her.
As the man is nearing ejaculation he pulls the thread, along with the attached piece of meat, which causes the woman to heave (convulse).
A side effect of the heaving is for the sphincter to contract violently around the man's penis, thus hightening sensations and giving a more powerful ejaculation.
"Damn it Daphney, that's the last of the bacon. We'll have to use the honey roast ham for our jibbing session this evening..."

Jibbing
This terms was used in snowboarding when riders ride on man made objects. Today, it is being used to desribe a certain style of mountain biking, where mountain bike hardtails with front suspension are often used to ride on stairs and benches and skate parks. For more info watch the movie Jibb. Some people want to call it urban mountain biking but the problem with this is that there are no mountains.
Normally a term in secondary schools in England seeing as most of the other definitions are nothing like what it means in school. It is the act of skipping lessons by hiding out somewhere usually in the school grounds. Most Jibbers usually are in groups of two to five. Jibbers are by no means bad kids, a lot of people jib the lessons they hate. Also if someone is off school for whatever reason then it is almost a necessity to say 'jibbing' when that person's name is called in the register, just to annoy the teacher.
