Someone initiates conflict with someone else without any provocation or warning
[note: Is it possible to have the full word be the title? The joke's kind of lost if it can't be the full thing.]] This is when either a person or a group (oftentimes a country) initiates a conflict on another without any provocation. While most wars are started because tensions between these two groups worsens, or because one group wants the other's land, food, women, etc., this is when the two groups appear to be on good terms and in general peacetime, when suddenly one of them attacks the other for no reason and initiates war.
