It has been an on-going “act of insult” in basketball (all levels, including municipal leagues) since circa 1982.
The “crossed-armed hatchet”, popularized by Brett Farve on the playoff circa 1990 is the same insult. (he faces the opposing bench and makes a “hatchet” move with his hands to his thighs while crossing his arms...can’t find the image right now).
IOW, it ain’t new, just being more recognized for its significance.
ugh
