The phrase "warts and all" means that you accept someone, including their faults and imperfections. It's usually used when you're talking about something or someone you like and accept even with all their imperfections. It's quite endearing. Ex: I wasn't sure I wanted a dog, but I quite like Spot. Warts and all. Ex: Are you sure you love me? Warts and all?
