"Lay about one" is an idiomatic expression that means to be lazy or idle. There are several synonyms that can be used to convey the same meaning, including laze around, loaf around, lounge around, bum around, and idle around. Each of these synonyms emphasises the act of being unproductive and spending time doing nothing. Whether it's lying on the couch watching TV, procrastinating, or just enjoying some downtime, using one of these synonyms to describe someone who is laid back and relaxed can help to paint a more vivid picture of their behaviour. So the next time someone accuses you of laying about one, just tell them you're simply lounging around.
