a) Torture, horrible torture equivalent to spikes shoved up the finger nails, slowly pealing skin off of a person, or hobbling someone like that scary chick from misery.

OR

b) A silly prank the military plays on their terrorist buddies at the big fun BBQ palace known as Guantanamo Bay
Example 1:

Bush is a total doucher for using waterboarding on those poor Muslims in his silly crusade again all religions other then his own.

Example 2:

Man, the military and those terrorists look like they are having so much fun over at their party. They get to bob for apples, play pin the tale on the donkey, have a tickle contest, and enjoy some fun waterboarding.

Taking a woman from behind in the shower while her head is under the flow of water, when you are close to ejaculation, pull her hair back swiftly so her head tilts back and her mouth opens. This will give her the impression of drowing, which will cause convulsions. Which will cause her vaginal, or anal, muscles to contract giving you more please and a sustained orgasm.
She was in the shower, so I nipped in, slipped in for an easy pink and on me vinegar stroke I waterboarded that bitch!

To waterboard is to choose a victim in a pool or the sea, quickly grab their ankles and pull them towards you so that water goes up their bum. Giving you an uncomfortable feeling which you won’t be sure if you enjoy or detest.
I was on a family holiday and my uncle thought it would be funny to waterboard me when I was in the pool. I never left the room for the last 3 days of the trip due to the sensation/discomfort
