The morning after a particularly heavy night of beer and Mexican food, when that one icy drop of water splashes back up after your drop a turd and it hits the exact eyelet of your asshole, briefly causing your breath to catch in your throat.
The finger of the dead just about made me jump out of my skin this morning!!
The wonderful 3 to 5 seconds before orgasm, but after the point of being able to go back. The connection is once WWII bombers were on a bomb path, they could not stray from it for any reason, known as the bomb-run.
I flew right up hair alley and commenced the bomb-run.
