When someone sends another person a meme out of context, usually by texting, and the recipient sends one of their own right back. This can be repeated, done in a group chat, or both.

Not to be confused with a meme dump, as this is done more casually and socially
Person 1: *sends meme*
Person 2: *sends meme*

Person 1: "that was quite a meme swap"
Person 2: "yes it was"
