It looks like it depends on the context. If your web page is actually making a statement about Victoria's Secret (e.g., "our products are as good as theirs, but cheaper"), then it looks like putting their trademark into your meta tag would be allowed as fair use. But just adding their trademark to your meta tag to get a hit when someone searches for them could be considered infringement, since you're using the trademark to confuse the consumer into believing that your site is somehow associated with their trademark.
