look up any word, like cunt:
the sexual act of lighting one's fart so that the flames lick the genitals of another.

In an extreme variant, the male genitals are doused in cooking sherry, which is ignited by the flaming blow, then extinguished by anal penetration. Done incorrectly, it can lead to fire in the hole.
She singed my pubes with that flaming blow, but it was totally worth it.
