Wakeboarders and wakeskaters sometimes use elements such as pipes, low docks, and tables as obstacles. This is also referred to jibbing.
Ladies and gentlemen, jibbing.
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.
