Origin
Probably a dialectal form of shame. Alternatively, sham is a term that is used to describe the bottom thick base of a glass, usually a wine or stem glass, where the stem meets the bulbous shape bowl. Glass manufacturers would increase the "sham" to deceive customers into thinking a glass holds more than it actually does. For example, a manufacturer would mold a 12oz glass with a larger "sham" in the base to reduce the volume of the glasses to fit 10-11oz of liquid. By increasing the bulge in the base, usually where the stem meets the glass, it is almost impossible to visually distinguish the difference.
