'XD’ is a commonly used Polish emoticon. Different capitalisations and the number of xs and ds influence the meaning. It was adopted from the West’s usage as an expression akin to 😆 when Poland properly embraced the internet in the 2000s, but unlike in the West it didn’t slide out of fashion and adopted more general, varied usage among Poles. Sometimes it is also used as a noun.
