bachsliding
the act of a married man reverting back to his bachelor ways when his wife is out of town; i.e. forgetting, or blatantly ignoring what his wife has 'taught' him not to do, such as leaving the toilet seat up, etc.
"Dude, did you notice Jay's house at the cookout? The dog was sleeping on the couch, everyone was drinking out of plastic cups, and there were no hand towels in the bathroom. His wife's only been away on business for a week, and he's already seriously bachsliding."
