Grandma Frosty 

The type of person youd find lurking around a social media app, disguising their user as "grandma frosty" they're a good, true friend who will stuck with you to the end. However, this is both a blessing, and a curse. A grandma frosty is almost always a crack head, or a pure clown. If you ever meet one, make sure to show them lots of kindness and support, as they are human like you, and need help at times.
