The spelling of the phrase "most dishing" is pretty straightforward. "Most" is spelled with the letters m-o-s-t, and it's pronounced /moʊst/. "Dishing," on the other hand, might be a little trickier. It's spelled d-i-s-h-i-n-g and pronounced /ˈdɪʃɪŋ/. This word is the present participle of the verb "dish," which means "to serve food in a dish." When someone is "dishing" something, they're serving it up, whether it's food or gossip. So, "most dishing" may refer to the most scandalous or juicy bit of gossip.
