One of the many forms of terrorism (in the form of torture) used by the US military in the "service" of putting an end to terrorism. Waterboarding (called "water torture" in the 16th century and used to test the witchiness of witches) involves holding a person down, covering their face with fabric, then pouring water on the fabric. The wet fabric makes it impossible to breath and the person feel as if they are about to drown, thus freaking them out to the extent that they will do just about anything to avoid more torture.
The CIA and US military use waterboarding to promote democracy worldwide.

Get the waterboarding mug.
When you ejaculate on a person's face, and the cum-shot ends up going up their nostrils, making it temporarily difficult for him or her to breathe through their nose. The reference is to the torture technique in which a victim is placed on a downwards sloping board, and water is poured into his or her's nostrils, simulating the sensation of drowning.
"Man, I just wanted to cum on her face, but I ended up waterboarding her instead."

"You can cum on my face, but don't waterboard me."

Unintended suffocation while giving head -- can feel like a form of waterboarding.
My husband was pressing on my head while I was giving him head and unbeknownst to him, his cock and my spit plugged up my airway. When I stopped to catch my breath, I exclaimed, "that felt like waterboarding!"

Waterboarding = guy standing, girl kneeling, shower running.

You can imagine it's pretty hard to breathe much less see with that much going on in your face. "Board" = pretty much self-explanatory.

A technique used to make godless rag head terrorists tell the truth. Drowning is simulated to make the subject feel they are about to die; thereby telling the truth to save their skins.
