A Penis. But not just any penis, must be a Boss. A penis that gets it done and has the confidence of a Banny Rooster. A cock of the walk. When you roll so hard and have so much swag you cock can get them digits from a waitress while you order a drink from the bar. When you text and drive your dick can take the wheel, so you can use both hands and focus on your tweets. That's a swagger dagger.
I rolled up to my girls house about 2 am and stabbed her with my Swagger Dagger. Ray's got game, but when when my ex rolls up with that swagger my panties drop by themself.
