These days it's not uncommon to hear the word Kanjar/kanjaḍa (कंजर/कंजड़) being used as either a sarcastic insult or a nominal derogatory insult against the other person.
However, as per Wikipedia:
The Kanjar are a nomadic tribe or group of people of North India, Kashmir and Pakistan. Some of them are Hindus.
Is the word "Kanjar" found in any canonical text either in reference to insults or as a group or tribe of people (like the malecchas or the chānḍālas)?
In what context is the word kanjaḍa (कंजड़) found in the texts?
