""Well, I guess if you had grown up with it, you would understand polo," Minx said snobbishly." The author implies this is undesirable because it's obvious that it's snobbish, but it's really not. The sentence could have easily not been snobbish. A good point in the comments was that the verb+adverb can often be replaced by another verb, eg. yelled angrily -> exploded. I remember seeing a big issue raised with the adverbs in Harry Potter, but I don't remember any problems with its writing when I read all of those long ago.
