HOW THE FRICK-- ok well basically if u memechat someone, basically someone can send u a link or you can memechat someone who has followed you. Once you get a link you'll see this little envelope thingy next to your notifications and then if it turns orange then that means someone chatted to u. Here is a link to memechat me ;): https://imgflip.com/memechat?invite=abWRiOUvZtttz94g6LPZBj-rEMAzZVCB
