Through a Lens Darkly

My godbrother is over right now. He's hilarious! "I don't need a map! I know this place like the back of my plawns!" I think he meant "palms". And then he freestyled for me:
My tricks are delusional, but are also destructive
I am a detective with a good perspective
I mow the lawn in nuclear grass
So come over here, so I can kick your ass
There's tears in my eyes from laughing so hard...
