The Twinkiesmoot is named in honor of Oliver R. Smoot. While a student at M.I.T. in 1958, Smoot lay down on the Massachusetts Avenue bridge between Cambridge and Boston, Massachusetts. His length was measured and that length became known in M.I.T. lore as 1 smoot. The term has become widely known and Google Earth offers it as an optional unit of measure. Note that since the twinkiesmoot is a measure of the rate of production, and the smoot is a measure of distance, the two are related in name only.
A related term is "nanotwinkiesmoot." A nanotwinkiesmoot describes the rate of consumption of twinkies by an individual person. 1 nanotwinkiesmoot equals 1 billionth of a smoot, or 0.00006 twinkiesmoots.
The two terms have entered general usage in the Boston, Massachusetts area. It is generally believed to have been coined by a student of the M.I.T. business school.
