Similar to the dirty sanchez, the Groucho Marx takes this ever popular anal move one step further. With the Groucho Marx, one takes his shit covered finger and applies a heavy coat of fecal matter to his lovely lady friends' eyebrows and then in the same move takes his shit covered dick giving her a poo-stache. After your gal has achieved the full Groucho Marx look, the gentleman can proudly exclaim "A woman is an occasional pleasure, but a cigar is always a smoke!"
"You think my girl looked good with a dirty sanchez? Wait till ya see when I Groucho Marx'd her!"

"Honey, I'm not in the mood for all the Marx brothers, do you think tonight you can just Groucho Marx me?"
