Etymology

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. This gives the illusion the glass size is the same as any another 12oz glass, but the inside will hold a lesser volume. Later, bringing use to the term "you got shammed" when one party tries to hide something and/or get over on the other party using deceiving tactics.
