Get the Wah Modiji Wah mug.
A popular slang in India which refers to a person who does something wrong and shows arrogance instead of feeling sorry. The word 'Wah' is a Hindi word for praising someone, in this case, it is being used sarcastically.
When a driver pulls over in the middle of the road to drop-off someone and blocks the whole traffic behind him/her and gives you a rude look when you ask him to clear the way. In that case, you can just say 'Wah modiji wah!'
