KLPD - Khade L**d Pe Dhoka
"Khade L**d Pe Dhoka" is used in a vulgar way to represent cheating by someone. Today, this phrase is used most frequently by teenagers in India, if someone cheats on somebody. It is used in form of an acronym but not in full form, because it sounds very vulgar in Hindi.
Origin of KLPD
The phrase came from Hindi films of Nineties and above, which gets abbreviated as a vulgar slang. It was first seen in a film where a boy is criticizing his male friend by using this phrase, when his girlfriend dumped him.
