The release of loud flatulence while urinating.
The old guy at the urinal had no qualms with a gentleman’s release. It was loud and repugnant.

I did a gentleman’s release earlier and I’m thinking now it may have been a little wet.

Get the Gentleman’s Release mug.
The passing of flatulence while standing at a urinal taking a piss. Typically done with one hand on the cock and the other arm extended against the wall for support.
I was taking a dump today and I don't know who walked in and did the Gentleman's Release but it sounded really wet.
