Also, we need to make a distinction between messy, and just flat-out dirty and/or nasty. If you've got some stuff laying around, and maybe haven't dusted or vacuumed in a little while, that's messy. If you've got spills/beverage rings on the tables, crumbs and old food laying about, and flies buzzing around the kitchen because you haven't emptied the garbage, that's dirty/nasty. If your bedroom smells funky because of dirty clothes laying around or in the hamper forever, that's dirty/nasty. There are two areas of your domicile that simply can't be less than clean - the bathroom and the kitchen. If those two places aren't reasonably clean, you're a nasty fuck. Other areas of the house, particularly your bedroom, can look "lived in," and only required some tidying up to receive company. If you've got to do a full-fledged scrubbing to make it presentable, you're nasty.
