Dirty Bertie 

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.

The Dirty Bertrand 

Similar to a Dirty Sanchez, when one lets their unwashed bellybutton begin to stink then picks said bellybutton and wipes it on the upper lip of an unsespecting victim.

I gave a girl the Dirty Bertrand last night, she threw up in her shoes.
