a port-o-potty; port-o-let; port-o-john; portable toilet. named so because port-o-poddees are found predominantly in construction areas where Mexicans are known to frequent and work and their resemblance to a ramshackle space shuttle.
No bathrooms on this construction site, just Mexican space shuttles.

Jose was in the Mexican space shuttle for an hour, I wouldn't go in there.

That Mexican space shuttle is dirty.
