Acronym for thank God it’s Friday, indicating one is glad to reach the last day of the traditional five-day workweek. Eric Partridge suggested that this semi-humorous cliché may have originated among schoolteachers, but by the mid-1900s it had been taken over by anyone who worked a five-day week. From about 1991 to 2000 the Boston Globe business section ran a weekly Friday column entitled “T.G.I.F.,” written by Alex Beam. New Hampshire’s Manchester Union-Leader also has one, and probably countless other newspapers as well. At one point, Beam said, he also wrote a column called “T.G.I.W.,” which ran on Wednesdays, but so many readers were baffled by this acronym that it was discontinued. T.G.I.F., on the other hand, definitely qualifies as a cliché.
