grandfathered friendship

To be friends with someone only because you’ve known them for so long.

You may not necessarily like the person they become and might even find their presence annoying but you still tolerate them because it’s just easier.

The only reason why she still tolerates her is because they are in a grandfathered friendship.

Sweaty grandfather

When someone is sleeping with their mouth open then you start doing immense cardio to get sweaty then you return to the person with their mouth open then swing your sweaty nuts in their mouth like a grandfather clock

Yo Isaiah want to give Matthew a sweaty grandfather

The Grandfather Effect

An term made by me at 3 am looking at minutephysics video about the grandfather "paradox"

The Grandfather Paradox is when you go back in time and kill your grandfather but since your grandpa is dead, you cant go back in time since.. u know... you dont exist. But since you dont exist your grandpa exists which means YOU exist but then you go back in time and kill your grandpa, and it keeps going on forever.

But in minutephysics video he talks about how it´s NOT an paradox (cant have links sorry)

Me: Have you heard of The Grandfather Effect?

Friend: No. What´s that?

Me: The definition is: If an action makes that action impossible, that action is both possible, and impossible. - Me 2020, it is kinda like Schrödinger's cat.

Friend: Ok, i understand now.
