urinalienation 

The act of a (usually) heterosexual male entering a pubic restroom and passing one or more open urinals in order to create the requisite "space" between himself and any other pee-ers.

Man: "Dr. I've got a bad case of urinalienation."

Dr: "Dude, me too! I can't pee unless there's three open urinals between me and other dudes!"

urinalization 

The mental process a man goes through when he enters a public restroom quickly heading directly towards his favorite urinal only to realize someone else is currently using it and must quickly make a decision on another urinal to use without upsetting the urinal etiquette balance.

Dude... I went into the bathroom and had an urinalization. It was a close call because I nearly had a urinal checkmate on my hands.
