OFTD stands for One For The Day. Used to indicate to a person used to telling bad jokes that he just told his one bad joke for the day and that he is done for the day.
Strange guy who likes wearing girl t-shirts: "I saw a butterfly without wings today. I poured Red Bull on it.Red Bull-Gives you wings". Cool guys: "OFTD- You are done for the day"
