The Drum Roll

When a woman farts in the seated position and the gas exits through the front instead of the back, becoming trapped in the frontal region. She then heads to the bathroom to shit and upon first push, produces a quif... The Drum Roll.

Harriet realized it was time to go when she let a short pre-shit rip out while sitting on the couch. She headed to the bathroom and upon sitting down gave a little push, and out came The Drum Roll before the big event.
