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