A kind of alleyway arms-race.

If you walk around Montreal with any regularity, you may have noticed the recent rise of an artistically rich and linguistically complex graffiti tag known as "Cobra Cock". Clearly a deep thinker with much on the mind, this street artist has shared his floral and richly original understanding of mankind by tagging many homes, businesses and alleyway fences with this overtly naïve approach to street art.

A particularly nuanced version of the ubiquitous Cobra Cock tag. 

Well, it's happened, as it was bound to. There is a new alliterated snake/genital tag in town. Behold: Viper Vag.    

Viper Vag stamped threateningly above a rather limp Cobra Cock.

I have no idea who did this - but you have my respect sir or madame - well played. As many Montreal property owners surely do, I look forward to the ensuing alleyway battles for space and supremacy.
