A cross between cornhole and burn. An atomic burn. To wreck someone completely. To burn someone emotionally.......twice. To burn someone a second time because they were too stupid to learn a lesson the first time.
Take a girl out and show her a good time. Get her interested, root her and leave before she wakes up. Take her number but don't leave yours. Leave it a few months before you call then ring, apologise, say you made a big mistake because you were too overcome with feelings for her. Next take her out again and repeat the first four steps. The end result is a cornburn.
