This word came about because of the laziest office assistant on the planet. She sits around all day reading gossip magazines and lets out a big sigh if you ask her to help you with something. She is usually sporting a pair of polyester slack with the tops of her granny panties showing. She never knows the answer to work related questions that are in her (job description). So, not only do you have to do her job for her, but you also have to figure out how to do it first. That's what I call sluggary. The act of being a total slug.
You have a lot of work to do, like rake the leaves, take out the trash, vacuuming, laundry, etc., but instead of getting anything done you sit on the couch in your dirty sweat pants eating a bag of cheese doodles and staring at the television. That's sluggary.
