Really awesome guy, tends to be someone you'll never forget, good or bad. Tends to be an asshole, but has a good heart when you reach it. Takes patience to handle, but can be someone you'll want in your life for the rest of your life.
Girl: I met a Jonn last night, he was a jerk, but I know what he's hiding.

Girl 2: what is he hiding?

Girl: A big golden heart!
