A sexually transmitted disease recieved from a partner your bro had recently finished with and so graciously passed to you. The origin of said disease is most likely, but not certainly, your bro. BroTDs are seen as a mark of honor.
Dude after Pat finished with this chick last night he let me have a go and now I have this weird rash. I think I lucked out and got a BroTD!
