Memes themselves imply a large audience coverage. They are funny, humorous, and understandable. But among a flock of white sheep, there is... not a white sheep. The role of such a non-white sheep is usually played by memes with subtle, graceful, but not always appropriate humor.
These memes are usually built entirely on sarcasm and irony. They keenly catch the flaws of a particular person, nation, or event. Of course, this is not the humor of an English aristocrat in the Victorian era. Frankly speaking, he is not even trying to be.
Such memes subtly point out various shortcomings and mistakes. The themes are very diverse. For example, the subtly noted racism theme is very popular. It seems like there was no intention to offend, but somehow it turned out that way. Some objects include Jews, African Americans, Caucasus residents, and ubiquitous Chinese people.
Such memes are quite often used to describe world political events. For example, on Russian-language Internet, politicians and residents of Ukraine, Belarus, the Caucasus, and Estonia are subtly targeted. It can be said that it is about the current pain points... The traditions of these countries in food and lifestyle, and the way of making money are also subtly ridiculed and emphasized. Among African Americans, Barack Obama is the primary target. Here, we can't do anything - he is to blame himself.
