A post-colonialist mindset which makes British people mistake the global spread of their language as the global acceptance of their lifestyle.

It is a consequence of ethnocentrism: (evaluation of other cultures according to preconceptions originating in the standards and customs of one's own culture).
Example: in an international working environment, during a meeting, British native speakers explain “how things work” to colleagues from other countries.
British native management person: “You should rather have answered I AM NOT SURE to our client instead of Saying no”.

Colleague: “Thank you so much for the britsplaining. The client is French and I am Turkish and we perfectly understand each other”.
