An old American Party trick that seems to have died out now,
Only ever Happened when considerably drunk or high.
It envolves covering the head of the "Victim" in Cling Film or Cellophane used for food wraping, while another person shits on the protected head.
The name "Warm Frank" comes from the warm feeling the Shit has on contact.
Dude, you hear that new kid dannys coming to the party tonight? Someone should so give him a Warm Frank.
