I find the assumption that girls are less messy than boys kind of naive and stereotypical. I suppose messy is ambiguous, does it mean clean or organized?
I remember living in the dorms my first year of college, and I was amused to note that the average boys dorm room was more organized and the average girls dorm room was cleaner. Of course, that is just my experience.
I find women are messier but also clean more. So more stuff left lying around but less grime. Where as guys will put stuff away but won't even know if there is a mop in the house.
Completely generalising here based on my own experiences.
If you are living in a house with 10+ people then it is going to be messy (messy being unclean at times) and if you can't handle that then you shouldn't live in a hacker house whether you are a girl or a guy. I was trying to make the point that I am a pretty chill person and wouldn't mind a mess yet people still tell me not to live in a hacker house.
