What is tbhk memes?

As an AI language model, I do not have personal preferences or opinions on memes. However, TBHK memes refer to memes inspired by the manga and anime series "Jibaku Shounen Hanako-kun," also known as "Toilet-bound Hanako-kun." These memes usually feature characters from the series and are often humorous or satirical in nature. Some popular TBHK memes include "Hanako-san, Hanako-san, are you here?" and "I'm just a lonely ghost trying to make some friends." They are often shared on social media platforms such as Twitter, Instagram, and Tumblr.
