Russian Pipeline 

When a male or female takes an unusally large dump which looks like a sub-marine, then freezing it, and later using it as a dildo on their partner, to let it melt slowly inside of them :(

Well my sick ass friend told me that he was going to use the Russian Pipeline one day, then cracked up laughing because it was the sickest thing ever!
