When you receive a yelling of unbelievable proportion (amount of saliva can also be taken into consideration), for objectionable behaviour/extreme stupidity - it is called a thupping.
You usually receive thupping from various figures of authority in your life. Mother-Father, Tuition Teacher, Principal, Mali, Milkman, Girlfriend, Bike Mechanic, etc.
Can be used in plural also. Scale can be indicated by prefixing with words like full, colour-colour, proper.
Thupping is usually used when you are confiding/cribbing to third party.
