It's another way to tell someone, out of anger, that you will put them in their grave, or 6 feet under if they screw with you again. It's a less direct way of stating it but still gets the point across.
After someone has double crossed or otherwise angered you: "Bitch, if you weren't somebody's mother, I'd put your ass to sleep!"

Get the bust a cap in your assmug. When an annoying idiot sits in their car, and blows the horn, instead of getting out of the car, and going to your door.
John got tired of the crackheads beeping their horn, so he yelled out the window "BLOW IT OUT YOUR ASS!!!"

Get the my foot in your assmug. 
Full phrase: "What crawled up your ass and died?" It is said after somebody farts and the smell is so horrible that everyone in the room runs out gagging. The implication is that the fart smells as bad as, for example, a rotting dead skunk or maggoty rat.
