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?"
A door wall is a sliding-glass door or patio door. The term is yet another example of banal Michigan vernacular, where in the residents latch on to company names, trademark names, marketing terms and product names from local companies. The terms become embedded in the local vocabulary and eventually become accepted as actual valid words and phrases. In this case the term comes from Wallside Windows in Taylor, MI (a large window manufacturer), where 'door wall' is their created word for sliding-glass door.
"Bob! John's gonna bring over them doorwalls from Wallsides on Tuesdee afternoon 'round two-thirty. Get 'er done!"
