When you have to break down the meaning of a current saying or word, so your granny can understand. You also need to say it LOUDLY!
Me: This party is lit! Granny: you lit what?? Do you need a match? Me: Let me Gransplain...This is a very exciting party. Granny: What? Me: GOOD PARTY!

When your parents tell you how to look after your kids. Back in their day they did things differently.
G: I brought up six kids and they all slept on their front. None of them died.
Me: Great, but times and advice have both changed. Stop gransplaining.

When someone of an older generation (typically a Baby Boomer) condescendingly explains why you are doing something wrong, even though they lack the shared experience necessary to equate theirs with yours.
"You don't need to go into debt to attend college. Just get a part-time job like I did!"

"Stop gransplaining me, Boomer."
