Take your fingers to the street to hit some people! Street fingers are for curling into a fist. And that street fist wants to do some hitting!
As you hit one chump after another, suddenly your dad (だ) comes marching out of your house. Uh oh. Dad caught you hitting, which, honestly, isn't a very nice thing to do, so he has every right to stop you.
