>>13023112leebaiting means posting MLP/derpibooru related content to trigger Lee, some actual schizo who hates MLP and is the very reason behind the "no MLP" global rule on 4chan
When someone posts ponies or screencaps from derpiboorus on certain boards, like /qa/ for example, Lee replies with a screencap that shows how MLP and Barney are aired on TV one after another thus proving that MLP is a show for children just like Barney. He also posts some generic death threats or some shit like that to the baiter, usually the same copypasted shit but from time to time he writes some personalized threat for the baiter, and then proceeds with replying to the bait with "kys" for several days or weeks even. He has been doing this shit for like more than 10 years now.
Also rembember that you're here forever, newfriend.
