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.
(to guy friend) dude last night while sheila was giving me a blowjob i totally gave her a dirty berty.
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.
God, I can't wait to get a Dirty Bertie.
