To say that an action is easy with out jinxing your self.

In some scenarios saying something is 'easy' is seen as temping fate and leads to bad luck - This phrase will get you out of many a sticky situation. For double refirmation or as a call and answer between two people it maybe used 'cool banana'...'banana cool'
Do you think you can get that done?

A phrase used to express your satisfaction with someones proposed course of action. The phrase was actually first coined by Simon Lambert on the 6th Floor of the Playford Builidng at the South Australian Institiute of Technology in mid 1984. Simon responded with "Cool Bananas" after one of the Malaysian students hacked into the Unibversity computer and changed all of the years assignment outcomes to the right answers , therefore saving hours of time trying to generate an R-squared in excess of 98.9%.
