Frosty Grandma

The act of, pouring an ICEE down an old woman's snatch and proceeding to eat it until you get a brain-freeze.

I went to a retirement home and gave this woman a frosty grandma.

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.
