Men's. You're the one who put the seat up in the first place because you can't aim correctly enough that you need a larger hole to pee in. Not my fault. And like Doc said, if you flush with the seat/lid up then all the **** particles will come flying out of the toilet and fill the room and get on you. That's filthy. You need to close the toilet lid so the **** particles don't escape, seriously.
In any other situation, it would be retarded for someone NOT to look before they sit. Would you not look at the seat before you sat down at a mall, school, movie theater, etc?
Yet for some reason when it comes to a frelling toilet it's suddenly TOO MUCH to ask for people to LOOK before they SIT?
The guy who used it before the woman. Sure it's not much for her to just look before she sits, but it's still good manners to do it for people who might use your toilet in the future.
