internal fart 

A fart that is denied acces into the world so in retaliation it runs back into your colon screaming,"I hate you!"
We know this diolouge as the sound of an internal fart.

As a fart tried to slip past my anus I refused to let it fly. It then turned into an internal fart.

internal fart 

A fart produced from the pressure due to holding a fart in for an excessive period of time. Makes the sound g'burgle. Sensations include feeling like your stomach will explode and extreme bloating. Always occurs in the presence of others.

The internal fart erupting in my entrails caused my face to turn red.

internal fart 

when you hold a fart for too long, and it finally pops inside your body before seeking its way outside. and after some time it slowly seeks out of your anus with a decayed smell that smells like old fart. (eg, could be the smell of a dead animal thast been dead for ages but still has not been cleaned up..)
