The word "gillooly" has a rather interesting etymology. It originates from the surname of an American athlete named Tonya Harding's ex-husband, Jeff Gillooly. The name became widely known in the infamous incident surrounding the attack on figure skater Nancy Kerrigan in 1994. Gillooly and his associates were involved in planning the assault, which aimed to eliminate Kerrigan as competition for Harding. The media widely covered the incident, and the surname "Gillooly" became associated with the scandal and deception. As a result, the term "gillooly" was then coined to describe an act of betrayal, trickery, or sabotage. It is worth noting that the word "gillooly" is not recognized in standard dictionaries and is used more colloquially to allude to the infamous incident.
