When a certain bet or sports events outcome is absolutely certain and without any doubt, that outcome is referred to as "Bill Guerin" or just simply "Bill" or "Guerin"
My team is up by 20 points with only 1 mintue left. It's "Bill Guerin" that they're gonna win.
This takes place when 3 gay men hold hands at the alter of a Catholic Church. While the priest and 2 choir boys tickle their balls and finger their asses and whomever cums first is the Georgetown Geronimo.
It is expected to yell “Geronimo” as you cum then the new “Georgetown Geronimo” is now crowned with the cum of the others. In the traditional sense a Priest would now pronounce this to his congregation.
