According to Catholicism, is ”damn” a blasphemous expression?

A lot of things in today's culture have names with the word ***"damn"*** in them, e.g., the restaurant Hattie B's Hot Chicken has a menu option named "Damn Hot". I'm sure it was a sin for whoever came up with that name, but what about for the rest of us? Is it okay for Catholics to use those names when talking about those things, e.g., while ordering at that restaurant, or would that be sinful too? If the latter, then how should we refer to them?
