Ring-around-the-roses is, as mentioned in the OP, a nursery rhyme. It is also a common children's game, at least in the US. The exact words vary, as is true of all playground rhymes, but this is the version with which I'm most familiar.
Black roses have come to stand for death and darkness. A person who has lost a loved one will often get a black rose tattoo to remember them. Those who just want their black rose tattoos to represent darkness will sometimes use other images, such as skulls, to make the meaning more obvious.
