This is an abbreviation for "just a mustache". It refers to the popular style of past of men sporting "just a mustache" without any other facial hair whatsoever. JAM was popular in many decades before the 1980s, but seems to have gone to the wayside since then. Often, men sport JAM in situations almost as a joke. This term was coined in the 1990s in Sarnia, Ontario and anyone who thinks they coined it before then may have done so concurrently, but not before me.

Get the Cock Jam Sandwichmug. A particular loving and caring moment to share with your favorite gal. First you place your fist in her ass, dick in her pussy, and palce you hand over her face blocking her mouth, nose, and ears (works best with either large hands or a small head). Once the convulsions start, the fun begins. Not recommended to hold the position for long and be sure to ask your doctor if you heart is healthy enough sex.
