Jacktivity 

The amalgamation of the word activity, and the British Army slang word "Jack" meaning selfish or lazy.

A jacktivity is something a multitude of people will do in order to evade hard work.

Person 1: "While we're in here, the smokers go outside every 5 minutes and evade the hard work."

Person 2: "That's such a jacktivity."
