Herbal flatulence

When you stick the top end of a bong up your ass and instead of your partner taking a fat rip they help you take a fat rip by blowing causing a fart.

Nathan- alyssa have you ever herbally flatulated?

Alyssa- babe what’s that
Nathan- lemme show you, show me your ass
Alyssa- but we’re busy getting high

Nathan- I know (;
Alyssa- WANNA SMOKE MY HERBAL FLATULENCE WHEN WERE DONE?!?
