The patch of hair on a man's lower back in the same area that a woman would get a "tramp stamp" tattoo. This patch of hair is typically the only hair they have on their back, and is often similar in size and shape to a tramp stamp.
When John took his shirt off, the man stamp peaking out above his shorts put Mary's tramp stamp to shame.
