The Jameson is when your engaged in sex doggy style. When your about to ejaculate you hit the poor little lady in the back of the head with a cynder block so she tightens while passing out making the orgasm all that more better (for you ofcourse).
As he was banging her doggy style he reached to his right, grabbed the hidden cyderblock and pulled The Jameson on her.
