The extinction of spurt is sad in itself, but it’s an increasingly familiar story of the pace of language. Just as “texting” and “selfies” offer a glimpse into how a technologically savvy Scotland now speaks, “sprunt” takes us back to a much simpler time.
So what does it mean? Basically: boys chasing girls around haystacks after dark. Possibly a portmanteau of “sprint” and “hunt” - such as these escapades may have felt for all involved - it not only reads like an activity straight out of a Boy’s Own manual, but it also suggests that it was done so often that “chasing the girls around the haystack” didn’t really cut it for a quick description.
You do wonder what the girls would’ve called it, though.
