Bernie Nicholls Season
This phrase is used to describe what is happening when a person is scoring with so many people sexually during a summer or a "season" that they know they could never repeat or duplicate the experience. This is based off of Bernie Nicholls, a retired NHL hockey player, who once scored 70 goals and 150 points during the 88-89 season, but never once came close to that amount before or after that.
"Dude, these days every girl you talk to seems to want to get your number. You gotta keep this streak up, as this is your Bernie Nicholls season!"
