When an individual is laying on his back masturbating, and just before he ejaculates, he rolls his legs up over his shoulders so the cum drips on his face. Also known as "pulling a deep abyss" because doing so can get you into such a deep hole of homosexuality, no degree of heterosexual acts or "no homo" exclamations can dig you out.
Person A: Sorry I'm late, I got caught in a Siberian Snowstorm.
Person B: What's all that white stuff on your face........?
