My mom insists on a “trendy” grandma name

M

I’m the oldest child in my family and over the past few years my moms friends have started becoming grandmas. They chose different names like Gigi, Mimi, etc. This led my mom to start her search for her grandma name. She ultimately has decided on Queenie, which myself and my 3 siblings absolutely hate the idea of. She even tried persuading my dad to be Arch Duke. He wants a traditional name like Grandpa, thankfully!!!! But my mom will not let Queenie go. Now that I am pregnant, after many playful arguments… I told her I really don’t like it and always wanted my parents to be Grandma & Grandpa to my children. I told her she should be proud to have the title & it is a life milestone! I feel “Queenie” takes away from it and makes it feel like she is not a Grandma. I think it sounds ridiculous. My entire family (siblings, aunts/uncles, grandparents, etc.) all make fun of my mom for this but I can tell she really gets upset about it. She landed on Queenie but says she is still searching for another name, which tells me she sees what everyone else is saying about it! But she is adamant “Grandma” is old and ugly. Which visibly upsets both of my Grandmas!! I remember years of her having no issue with Grandma. That is, until her friends started choosing “trendy” names. I feel like she’s being a poser for lack of a better word & just trying too hard to be cool and fit in with her friends. She always prioritizes her social image above all which drives me crazy. I’ve explained to her my kids and my siblings children will never find a picture frame or a Christmas ornament with the words “Queenie & Me”, etc. on them! She just simply does not care. She literally says she wants something “young” and “hot”. It’s annoying. She is going to be 50!! She keeps saying it doesn’t have to be Queenie, but yet vetos every other option. My husband hates it, I obviously hate it. My siblings are relying on me to put my foot down with her. And it is the joke at every family gathering. She’s honestly causing me stress with this. What do I do?
