look up any word, like blumpkin:
 
1.
A shower usually taken with really cold water. Named after the frigid showers that inmates at a Siberian prison are forced to take daily.
My freaking landlady forgot to pay the gas bill, so we were forced to take a Siberian shower. That shit was COLD!

Man, my penis was all shriveled up after that bitch made me take a Siberian shower. I think my penis got hypothermia after that.
