Diggity Dope. How am I supposed to say it? It's the perfect phrase. Every possible situation that you could ever imagine could use a solid 'diggity dope'. Think about it. A wedding, a new dog, a comedy club, a light hearted funeral. All situations could use a little 'diggity dope'.
Used as another way to say: okay, right on, cool beans, sounds good, etc. Can be combined with other words to demonstrate excitement for a certain thing.
