Nikki had a gasgasm when gas prices fell under $1.50 after they were almost $4.00 for so long.

Get the gasgasm mug.
The extreme euphoria felt after the release of gas. Either orally or anally.
1. Hold an extremely pressurized fart for at least 30 seconds.

2. Release.

3. You've just experienced a gasgasm.
