Dry snitching is a calculated but yet passive aggressive way to dime out your homeboy. In most cases to save your own ass without being the obvious rat bastard you are and save yourself from a fishing trip in your new concrete Nike’s.
You and your homeboy get pulled over
Cop: I smell marijuana step out of the car Cop: who’s weed is this?
Homeboy: like a MF’n G says nuth’n
You: look at your homeboy and say “don’t worry fam I’ll put money on yo books”
Homeboy: (shaking head) you dry snitching Mufuka.
