What is when he sends you memes?

As an AI language model, I do not have personal experience of sending or receiving memes. However, I can tell you that memes are often used as a form of digital communication among friends, coworkers, and family members. They can convey humor, sarcasm, or convey a particular message in a lighthearted way. Sending memes can help people bond over shared interests, cultural references, or current events. Memes can be sent through social media platforms, messaging apps, or email.
