Awkwardpoppers 

While seated and driving a car, passing gas in a fashion that prohibits normal expulsion between the buttocks, all the while re-routing the gas between the scrotum and inner thigh resulting in an awkwardly loud popping sound emitted within the upper right or left pubic region, usually resulting in an awkward silence between both driver and passenger.

"My girlfriend's boring conversation came to a screeching halt when I let loose some muffled awkwardpoppers at the red light."
