My dick is bigger than your dick

My Singaporean friend can be annoying at times. He asked me why I am so small size? How the fuck am I suppose to answer that sort of stupid question? Can I ask my mum why my dick is so big size? Then he go on and on that Singaporean guys are so well built and big sized bla bla bla. Yeah lah, I know I am small sized, don%26#8217;t rub it can? So I told him this:-

Every guys in Singapore has to undergo the gruelling national service but in Malaysia we only have self service. What self service? Well, you know I know. If you don%26#8217;t know then congratulations. You have a pure untainted mind.
