A Kyler
A Kyler is a long-term disease you catch from hugging and kissing your best friend. He thinks he's hilarious, but he's just annoying.
Kyler: "I'm hilarious. You're just too stupid to see it."
Kyler: "I kissed my best friend and now I'm infected with Kyler disease."
Kyler: "I'm so confident in my sexual jokes, I think I'm a comedian."
