A heavenly biscuit occurs when a man copulates with a pregnant woman ("bun in the oven") that has a yeast infection. The intercourse involves so much yeast that a chunky "halo" is revealed, circling the outermost point of penetration on the man's penis.
Jeff was really excited that this pregnant chick was DTF, but he sorely disappointed after he realized he was a victim of the heavenly biscuit.
