Etymology

Cognate with French: glisser

In summary

Probably from Yiddish גליטש (glitsh), from German glitschig (“slippy”), from glitschen (“to slide, glide, slip”) + -ig (“-y”). Related to gleiten (“glide”). Cognate with French glisser (“to slip, slide, skid”).
Popularized in the 1960s, by the US space program. Attested in 1962 by American astronaut John Glenn, in reference to spikes in electrical current.
