1 Humour, because people having different cultural tracks interpret it differently, is culturally unique; however, it is global; though.
Humour is a universal activity, but also culturally specific since people from different cultural backgrounds may perceive humour differently.
2 British people probably mock with not only themselves but other people as well; they, nonetheless, seem unsmiling people.
Even though the British appear pretty serious people, they are more likely to make fun of themselves – self-deprecation– as well as the others.
3 Especially, British people deprecate –covers not more you figure out or
feel–anyone to make them feel silly in undesirable and cringy conditions.
They use irony which means saying less than you think or feel, in particular, in unpleasant or difficult situations to make someone look stupid.
4 Instead of ridiculing the condition via overestimation, slighter understatement is emphasised because of their noticeable humour.
Inasmuch as humour is open, rather than satirising the situation through exaggeration, less emphasis on understatement is seen.
