A large group of chavs and chavettes walking down the street or hanging around on a street corner, smoking and sometimes drunk. Like an avalanche, you may get swallowed up bt the crowd, and possibly killed by the cloud of smoke and cheap perfume that lingers! It is recomended to stay away if at all possible!
'look out mate'
'what'
'that, quickrun!'
'help us...chav-alanche!!'
The result of a crappy band name maker, Penis Avalanche is the name of the dopest jazz band in the northern hemisphere. Playing hit singles such as "Trunk of the Pussy Spray" and "Fuck Mel Gibson" the band has quickly gained success as the number one band in Albion, Washington.
The band has since broken up, and reformed so often, that most of the members have no longer play an instrument and instead stare awkwardly at each other for the better part of 12 hours while watching hipster music videos on Youtube and making fun of their poor bass player.
When a man stands behind a bald person on their knees and slowly cums on the top of their head so it will run down the persons face, like an avalanche runs down a mountain.
