The act of forcefully shoving someone's face into your ass and farting to the point of shitting your pants.
"Hey Greg, take this! kamehameratio"
When there is extremely heavy snowfall.
Usually without warning and from seemingly nowhere.
Called such due to Siberia's harsh weather conditions, particularly pertaining to snow. It's always snowing.
Therefore, any snowfall in a country not used to snow, has a Siberian Summer whenever there is snow. Doesn't have to actually be summer.
Fuck sake. When I went to bed it was dry as a wood chucks asshole. Now I've woken up and there's about 6 inches of snow! What is this, a Siberian Summer?
