To appear presentable after grooming oneself. This is a set phrase used to compliment one's appearance. However, because it implies that one was previously dirty or unattractive, it can be received as an insult or backhanded compliment. Did you see Owen in his suit and tie? He sure cleans up nice! All I said was that she cleans up nicely, and she got mad at me!

euphemism One who has died. Myrna was a wonderful woman, and we are all gathered here today to remember our dearly departed.

To do something in isolation; to act without the help of others. Primarily heard in UK. I tried to offer Jonathan help with the project, but he'd rather plough a lone furrow.
