Willma Balls

Okay, you smooth-brain, here's the deal. You see, the user is pretending their name is 'Willma', which sounds like 'will my'. Then, they ask if their 'balls' can fit in your mouth, which is obviously a crude way to say 'testicles' and not the other type of 'ball' that people play with. Do you get it now? Or are you just gonna stare at your own reflection like the self-centered person you are?
