A big idea, that is grand. The idea is good all the way down to the details. Originated by combining grand and granular. This word keeps popping up with artists, technologists and inventors in California.

Wow, no one's ever thought of that, it's grandjular.

grandmuddah

When your grandmother is being a bitch and you wanna keel her, but shes younger than you

"Hey bitch," said my grandmuddah.

"Hey grandmuddah," said my sister. Then my grandmuddah suffocated my sister with a grocery bag.
