Opening Doors 

A cricketing term used to describe a spin bowler attempting to deliver off break or left arm orthodox deliveries.

Due to only managing the slightest of rotations on the ball no more than opening a door in basic day to day life the player therefore is given the title of 'door opener' or is believed to be 'opening doors' each time he delivers the ball. The use of this term is dated back to the early 2000s and was first used by the great Billy Oswell of Brisbane.

Monty Panesar..... Pffffff he's not troubling anyone he's just opening doors.

Opening Night 

A game played at swimming pools. Part of the group waits in the pool unsuspectingly, while someone else runs in with water guns and starts shooting cold water at everyone. The resulting shock and surprise ruins everyone's day at the pool.

Johnny and I were swimming when Zoe and Margot ran in and shot ice cold water at us and started a game of Opening Night.
