a ring doesn't plug a hole
A ring doesn't plug a hole means a married woman is still looking for a new man to fill her hole while her husband is out getting drunk.
My wife got a tattoo of her new boyfriend's name. I got a tattoo of my ex's name. I'm still married.
She married my dad, but now she's cheating on him with my brother. Classic.
My aunt got a ring, but she still sleeps with the mailman. The mailman got a ring too.
