How to irritate your friends?

Ok, the easiest way I have done it is be an idiot. Everytime when you mean to say shit say poop instead, or for -blam!-ing say fudging and it will slowly begin to irritate them because your talking like an idiot. Also, everything you see a engram/gear drop whether your in a dungeon or heroic just run out and scream SHINY and run back after grabbing it to give your friends a heart attack or a good laugh but keep doing it because eventually they will become irritated....I do this for shits and giggles but when someone else does it for worse its not fun when someone giggles and shits...
