Moaning Zombie
An entertaining way of concluding business during sex. Ensure you are banging a girl (preferably someone who loves you) from behind, and then spit on their back.

Proceed to pulling out of your partners quim, spinning her around and then hitting her in the face with the money shot. Her reaction will be the perfect impression of a moaning zombie (as in, cum = melting flesh, moan in response to your actions).
Yesterday, I moaning zombie'd your mum.

This fat bitch was fucking me off during sex, so I hit her with the moaning zombie.
