I just realised there are classifications of memes on the internet

• Immortal: Usually slang that evolve to casual use if it's even considered a 'meme', but not many memes stay relevant for years so pretty rare
• Long Term: Memes, trends, slang that stay for many months or years
• Short Term: Memes, like photos, or usually videos or a group of videos, or audio that last a few weeks before dying off
• Posts: No lifespan, usually from a template or something else, usually pictures
