Otherwise known as "slush fucking," the Siberian Chill is the act of pouring a fresh, ice cold slushie drink down a girl's anus and using it as a lubricant for anal sex.

(Warning: May cause your penis to go flaccid due to cold temperatures and may give the girl an extreme "brain freeze" sensation in the anus.)
After purchasing a slushie at the ice rink, Bob desperately wanted to try the Siberian Chill on his girlfriend because he was in the mood for something kinky and thought it would make his girlfriend's anus taste like berries.
