There is a point in the night of drinking when you have passed the point of no return, or you have launched. After you have launched are bound to black out, be an ass, or get into a fight. If it looks like your headed in that direction you might be able to refrain from that last drink that would put you over the edge and effectively abort launch.
Kellee told me to abort launch after she witnessed me double fisting two whiskey rocks.
Eric didn't yeld to my warnings to abort launch and ended up hitting on everyone at the bar.
