Womblingo
When you are surrounded by wombles who are ruining enjoyable or constructive conversations by wombling about nothing the only way to retain your sanity is to play womblingo. Each time the same (or agreed) idiotic or irrelevant story or phase is repeated you scream "womblingo", slap the offending wombler across the face and walk casually from the meeting or water cooler conversation (alternative: "womblingo", slap, stare them dead in the eye and slowly sit down again)
WombleA "......and thats how I completed my full set of Smurf miniatures", PersonB "Womblingo!!!!" SLAP, causal exit saunter
WombleA "........ and then I lost 10k on the slots machine", PersonB "Womblingo!!!" SLAP, steely stare, slowly take their seat again.
