Need not be a 'tactical' dragon, or even an alcohol induced dragon, whenever u feel the need for a good chunder,, just make sure its a 'dragon'.
Man 1 - "Fuck man, i can't skull that!!"
Man 2 - "just do a tactical dragon and get on with it you pussy'
Scenario 2 - during drinking game, perhaps 'never have i ever'
Jacob - "I think I'm gonna spew"
Everybody 'DRAGON!!!!!!!!" DO A DRAGON'
