look up any word, like kappa:
 
1.
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.
