Even if you don't know your name, it's extremely unlikely that you haven't seen a meme. Typical phenomenon of mass culture on the internet, memes are images (private photos, movie captures, etc.) to which fun and irreverent phrases are added and later shared on social networks. If done well, a meme can go viral and gain lots of sequences and pardies.
A number of Google Play Store apps make it possible to create memes. I recommend the Meme Generator Free. Despite being in English, it is very simple to understand:
Meme Generator Free
By opening the app you will be able to choose from a number of images already known from the meme world, or then use a photo from your gallery. Click on the chosen image.
