Although not pleasant, we can all foresee circumstances - turbulence, 'split stream'(!), etc. in which pee hits the floor. It's the pee on the toilet seats (in the air and on the ground) that I find more baffling!

Weirdly I've noticed this on all Boeing aircraft on any airline.

Umm, you cannot blame this on males.

Many females hover over --instead of sitting on-- the seat.

people who pee on the floor in from of urinals must have small wangs.

In this case yes, I can absolutely blame it on males, since only 3 people used the lav before me. They were all men (or very convincing).

To those who admonish others for going to the lav barefoot or in socks ... OMG, just stop that. Unless they are your actual children, you don't need to be their mother. Feel free to sit there in judgment of them, however, if it makes you feel better.

This coming from one who does wear socks to the lav - but only the throwaway socks provided by the airline in business or first on long-haul flights. Pretty much everyone does, and the lavs are generally pretty clean up front anyway.

Do people actually do that? Lecture complete strangers on aircraft about what they wear on their feet to use the lav? :confused:

Wonder how often they are told to MYOFB?

I think there is a big difference between cringing when seeing someone walk into the lav in bare feet, and actually saying something to them. I do the first, never witnessed the latter.

And a sign for the ladies
 

Some of it may be that airplanes induce anxiety peeing.

1) I am in the window seat, everyone else got up to go, this is my only chance. I must go now.
2) The food cart is going to prevent me from using the restroom for next 12 days. I must go now.
3) The plane is going to land and it will take six hours to deplane. I must go now.

In these situations, one may not really HAVE to go so the pressure behind the stream may not be in full force. I don't think this can be avoided.

That is a fascinating theory! You should consider publishing it :-)

Honestly, I just have a strong compulsion to mark my territory.

Although a port-o-potty by size measures is more spacious, I wonder if they would ever consider adding those funnel style urinals on the side of the lav like that have in port-o-potties. The space issues is the main concern, but this would greatly reduce "splatter." I would think.

Man, all our secrets are coming out... Territorial nature, split streams, low pressure, just poor aim...
