ATF 

ATF or Alaskan Thunder Fuck. Large and rather dank Marijuana grown in northern portions of North America. Characterized by its long lasting nugs. This is made possible by the long days of the northern summers and thus an extended intense growing season.

Tom matched three bowls of Chronic for one bowl of Mark's ATF.
