When you grab your dick and squeeze it until the head turns purple, then mercilessly punch the head or with a purple mallet/hammer. This act is usually done intoxicated and was originated by New Hampshire's own Matthew "Bordmatt" Warriner.

During the act of fallatio and/or post intercourse, when the male is about to ejaculate,said female and/or male, in an act of anger and/or hostility grips tightly upon the penal organ thus preventing the excretion of semen, resulting in "Jamming the Hammer" aka "The Jam Hammer"
