"Dope" doesn't sound like formal English. Do you use it often?

"Dope" in this context is highly informal, you're correct! The word has several different meanings, but I'll only explain this specific one in this answer. "Dope", as an adjective, means that something is excellent or highly-desirable. It can also be used phrasally as "that's dope" to modify an entire sentence. Ex: They're giving out free pizza at the gym today, that's dope! Ex: My brother has such dope sneakers, I want the same ones!
