A promise that every year on Saint Patrick's Day two or more friends will go on a walk while smoking a cigarette, even if they loathe one and other they must do this.

This is almost like a task to those who take the oath.
Friend:"Are you and -insert name- going to follow through with the St. Patty's Day Pact?"

Me:"We hate each other, but it has to be done."
