sidewalk shitter 

a person who defecates, usually out of dire necessity, on public walkways.

When going out in L.A., you're lucky if you don't have to pay to pee. Therefore, it shouldn't come as a surprise when nature calls and a sidewalk shitter starts doing his business out in the open.

Mexican Sidewalk 

A woman who is so amazing in bed that you swear she not only used the three main holes to satisfy you, but actually took it in up to SEVEN different holes from every angle. How did she fit it in her ear?? Did she use her knee pit at some point?? When she turned the lights off did I fuck a Stretch Armstrong doll rolled into the letter "O" or was that her asshole????

Derived from the ankle-breaking sidewalks of Mexico City where holes appear out of nowhere and walking three blocks is the danger equivalent of a WWII Belgian minefield.

Guy 1: Soooooo Jeff, I see you left the party early last night with that cute but square little chess champion who reads teenage vampire novels alone in the corner. How did it go?

Guy 2: Dude, you'd never have guessed it but turns out she performs like a Mexican Sidewalk!! *eyebrow, eyebrow*

Sidewalk Phalanx

If that sidewalk phalanx does not let me through I might have to walk in the dirt!
