When one man gauges his urethra to a size formidable enough that a man with a smaller, thinner penis inserts his penis into the pee hole of the larger penis. Aka extreme docking.
"Hey there Billy, I see you've got a pretty tiny dick and it would fit inside of mine quite well, let's have us a Texas Train Station"
AKA extreme docking. The act of one man inserting his penis into the piss hole of another man's penis.
Hey Samuel, that's a pretty tiny dick you've got there, I've been gauging my piss hole just hoping I'd find a man with your size dick so you can stick it in mine and we can have a proper Texas Train Station.
