cruckle

verb

1. (dialectal, intransitive)To stumble after inverting or everting one's foot; to roll (but not necessarily sprain) one's ankle.

   “The resident, who does not want to be named, was walking along the street on Sunday (1 November) morning when she suddenly cruckled over on her ankle and fell on her hands, resulting in cuts and bruises.”

   “As they continued she tried to think what to do and pretended to stumble, after which she faked a slight limp. ¶ ‘Stop pretending to limp.’ ¶ ‘I'm not pretending. I twisted my foot when I cruckled.’”

   “The slip said: "Holly cruckled whilst running" and he had no idea what it meant. […] Apparently, as many of you will already know, it means 'going over on your ankle'.”
