A casual greeting local to the Ventura, CA area, 'Shally' can be used otherwise as an expression of admiration, joy or occasionally light flirtation.
Pronounced Shall-ee, with the stress on the second syllable, when spoken the speaker often adopts a winking, card-games-and-cocktails like tone.
Shally rose to prominence in 2019 featuring in several viral Tik Took videos - however its original genesis is believed to come from a contraction of the name of beloved Dallas Cowboys linebacker Sean Lee. Other possible origins include the Hindi word for 'surgical' ('shaly') and the mispronunciation of the French word for a luxury mountain hut.
