Grand Parent

The parent post of the parent post.

[loloquwowndueo]

The very definition of a grandparent :)

[paulmd]

every time you reply to a comment someone else makes on one of your comments, you are in fact your own grandparent

[lucb1e]

Which is why you can't travel to the the parent post and delete it from history. This keeps the universe working in correct order.

TIL a grandparent is actually an internet comment, not a person
