Ask them if they want to learn the "sahee angrezi naam" of the item - also tell them that there is a difference between a doctor and a qasaai - for qasai a muscle becomes "machlie" for a doctor its tissue.
One charges tens of thousands one does not
If they are jokers - move along - they dont want to learn, e.g. ask them if they have heard about "sunlight switch" - sunlight switch is a term used for the external starter solenoid that was found in the ancient mazda 1500, mazda 800 etc. - people eventually butchered the word solenoid that it became "sunlight"
there are tons of other names I can tell you.
