CoughBoff 

Farting and Coughing at the same time to mask the sound of the fart.

Rob is watching TV and he didn't want to fart in-front of his newly acquired Girlfriend but he really needed to so he Coughboffed. Coughing whilst farting.

Jill could still smell it though. It's not quite perfected yet.

coughbowl 

Done when smoking pot from a water pipe;
When someone coughs into the bowl, causing the water to rise up the stem and ruin the bowl.

{P1} Lemme hit it again.
{P2} Sure, but don't cough into the bowl this time.
{P1} I'll be sure to hit it less this time, so I don't cause a coughbowl.
