Phrase used to describe idle mischief being done by someone that usually leads to a breakdown of the thing or person undergoing ungli treatment. Ungli karna is always unwanted but gives pleasure to the person doing ungli. "Ungli" here literally means finger.
Terko aur kuch kaam nahi, chup chaap ungli karte rehta hai.
(You have no other work, sitting quietly and doing ungli....)
