A form of flirting using words via the Urban Dictionary which has the potential to lead to positive fireworks or firewalls in a potential relationship. One person humorously enters a word and definition in the Urban Dictionary as a flirtatious diss and the other responds with an ever better one and so it continues and one day............all hell breaks loose and/or they marry. It's a testing type of relationship, testing of the minds and intelligence.

"He told me that 'West Africa' meant buttsex with a relative, and when I checked Urban Dictionary, it said it did. But I suspect some definitive urban warfare has taken place."

Urban Monkey Warfare occurs when a large number of crazy, possibly diseased, monkeys invade an urban area and proceed to systematically attack the human population. The humans in turn have no choice but to defend themselves, and the army is called in, turning the urban areas into large battlezones. The biggest ever Urban Monkey War was fought in Minto, NSW. The humans ultimately won, but both sides sustained heavy losses.

Urban Monkey Warfare is also the title of a song by KMFDM.
"If you see a large number of crazy monkeys near your house, prepare for Urban Monkey Warfare!"
