A petrol station is one of the dirtiest types of parties. It involves all attendees inserting enemas followed by tubes into their anuses. These represent the hoses at a petrol station. When someone feels it coming they scream "PETROL" and swing their tube round in the air.
That was a wild petrol station party last night... I needed 5 showers afterwards!
