You're a cakesniffing, mouth breathing, scruffy looking nerfherder.
Dam I thought I knew what the worst comebacks were but you don't just take the cake, you eat it whole, spit it out and throw it out the window. If I didn't understand what I just wrote then explain this. The first part was saying that you're worse than me and the second part was saying even trash, something that is not alive or sentient and does not have feelings or emotions not to mention no one likes it, wouldn't want you and that's a really rough insult. Checkmate.
(that's fine. It's all in good spirit but if you don't want to continue that's okay.)
