My girlfriend was laying in bed because her head was spinning from the vodka she drank so I had to have her stand up to give her the grundle stiltskin she would never forget.

Get the grundle stiltskinmug. by Vanderweasel September 24, 2019
Get the Moose grundlemug. During a fart, when air is compressed between the grundle and a hard surface- the air erupts to the nearest exit, usually out the front of the crotch. It is thunderous, not just for the thunderous noise it makes, but also because of the unsettling direction of the blow.

Get the Grundle Schnacksmug. When someone is rubbing your grundle or sack area intensly, and you chafe to the point of bleeding and then you let out very thunderous bloody shart onto your partners face.
