Dave, I think the difference in how the term is interpreted may depend on which side of the pond one is on. I find Leeneia's list to fit my understanding of the word "bully" as it is used in the US. Synonyms would be intimidator, browbeater, and I would add scold. We're talking about an online environment, not in person where some of the words with a more dense meaning come into play (tyrant, persecutor, thug, heavy, ruffian, etc.)

Euphemisms will abound surrounding Kate's surgery. There are so many possibilities, not just the usual "lady parts." They said this morning she hasn't been seen in public since xmas.
