The act of gooning until orgasm, then sealing one's penis hole using a thumb, glue, ect. to keep the ejaculate within. This can be repeated until it is all wished to be released in an act known as "blowing the dam." To date, no human has successfully attempted damming.

Get the Dammingmug. The act in which a person places a rubber bung 2.4inches deep in their asshole at 12:00 am on December the 1st. The person then proceeds to glue or tape the bung in place. Then without breaking or removing the bung to prevent the release of faeces from the body. Then at midnight every day bring the bung out 0.1 inches every time until on Christmas Day or 25th December, take it out in which an oil like shit stream will be released like an oil filled dam.

Get the Beaver Dammug. 
When two guys bang in the back of a John boat. They position themselves in a way that makes it appear to others as if they’re about to “jump a beaver dam”
