When one goes to a foreign city and hookups with a stranger within 12 hours. The origins date back to out-of-town gay men flocking to the Manhattan neighborhood of Chelsea in order to find a quick hookup before they return home.
Only problem with my tiny elite college in the middle of nowhere is that I always have to go to the City or Yale for a Chelsea 12-Hour; I need a bj even if there are too few gays on campus.

When you get a boner in public and flip your cock up into your waistband.(It feels good so try not to bust a load into your bellybutton.
"Dude I was in class and I was thinking about Gabby Bedard and Brandon Smith cuz I'm bi, and I got a boner so I did the 12 O' Clock Tuck. Works everytime. No one knew I had a boner. Except I did bust a load into my bellybutton cuz it felt good." said Tucker Kreis
