Adding feces into the strawberry shortcake. Specifically, a man ejaculates on his partner's face, punches his partner's nose causing bleeding, and defecates on his partner's face. The resulting mixture of semen, blood, and feces is what is required to characterize this sequence of actions as the 'Neapolitan' maneuver. Conceivably, a woman with the ability to 'squirt' could perform a similar maneuver on a partner.
"Man, last night I skeezed on my girlfriend's face, then punched her in the nose, then shat on her face."
"Oh, sweet, you gave her the Neapolitan!"
