Youthful ’signage’ attributed to CLUELESS
The Independent (U.K.) has an article about “signage,” slang hand signals used by young persons, attributing it to the film CLUELESS:
There are two schools of thought as to where the phenomenon originated. “Kids say they first spotted it in Clueless,” says Kathleen Pingol, a UCLA humanities student, who’s studied what she calls “the signage thing”. The 1995 movie, which rewrote Jane Austen’s Emma as a story of Valley Girl apotheosis, offered the first sightings of the three cornerstones - the canon, if you will - of modern signage.
The Editrix remembers making the International Sign of the Loser in her university days, back when Cher Horowitz was driving Barbie’s Dream Jeep into Josh’s GI Joe trucks, so we are taking this with a grain of salt.
