I still get it but not sure why she would keep that sign in her adult bedroom and on the wall.

Here’s the short, honest advice: Do not overthink this, and absolutely do not ask her to take it down.

Here is exactly why she keeps it, and how you should handle it.

1. It’s not about sex; it’s about sisterhood and hype

Yes, you get the innuendo. But to her, that sign is not a measurement standard for you. It is a trophy from a specific, formative era of her life. In sororities, pre-game rituals are all about building confidence. The "main chick" taking a hyper-masculine, serious movie line ("Strength and Honor") and turning it into a hilariously absurd, crude phrase ("Depth and Girth") was the ultimate inside joke. It was their way of saying: "We are taking the piss out of male bravado, we are hyping each other up, and we are about to go have fun."

When she looks at that sign, she doesn't think about penises. She thinks about her best friends, laughing until they cry, doing each other's makeup, and feeling invincible at 21.

2. The "adult bedroom" argument doesn't apply here

A bedroom is a private sanctuary, not a corporate lobby. Adulthood doesn't mean you replace every quirky artifact with a beige Etsy print of a botanical leaf. Keeping that sign actually shows a green flag: she is secure enough in her adult identity to unapologetically display a silly piece of her past. She trusts you enough to explain the backstory without sanitizing her history for your approval.

3. The sparkly "girl script" is part of the irony

The juxtaposition of bubbly, glittery script with a crude double entendre is precisely what makes it funny to her. It’s ironic decor. Taking it seriously ruins the joke.

What you should do right now:

Say this: "Okay, that is actually a way funnier backstory than I expected. No pressure on me to live up to the motto, huh?" (Say it with a smirk).

Why this works: It shows you aren't threatened, you appreciate her sense of humor, and you're confident enough to acknowledge the double meaning without getting insecure.

What you should NOT do:

Do not ask her, "But why keep it now?" That implies she should be ashamed of her past or her sexuality.

Do not ask her to replace it with something "more mature." That will make you look controlling and insecure.

If you two eventually move in together and you want to redesign a shared space, that is the appropriate time to gently negotiate wall art. Until then, let her keep her Gladiator-sorority battle cry on the wall. If anything, use it as a funny conversation starter with her friends when they visit—they will love that you knew the backstory and didn't get weird about it.
