a dirty berty occurs when your partner is giving you oral sex under a blanket and you fart and hold them under the blanket to continue while they smell your fecal odor.

When a man is receiving a bj, before he comes he places the tip of his penis into the female's nostril. He then ejaculates into her nostril, she inhales the sperm and spits it out her mouth.
