A urinal between two occupied urinals that is left open to avoid crowding and embarrassing misunderstandings
Alien: Why do human males only use every other urinal?

Guy: So strangers won't see our cocks or think we're looking at their cocks. We call the empty one "the sacrificial urinal."

Alien: Why is it such a big deal to see each other's cocks? Or why can't you just say "I'm not going to look at your cock if you don't look at mine?"

Guy: I definitely wouldn't believe somebody if they told me that, plus it offers no protection against bumping into each other.
