This is a combination of the words tonight and tomorrow. It has a very specific usage. It refers to something that is both the next day and later that night at the same time at about the hours of 11pm and 2am. For example, if you have a night job at a business, such as a hotel or a shift as a security guard where your work day starts at 11pm you can in the shift before your next, refer to your next work shift as tonighrrow instead of tomorrow or tonight since your work shift encompasses both that later night and tomorrow at the same time. Since you are starting work at 11pm it's only one hour into your shift before it becomes this days' tomorrow, so if you are talking about this time frame in the morning or afternoon as you would any other time you say "tonight" then that sweet spot in between 11pm and 2am would be tonighrrow since the activity or thing you are referring to encompasses both tonight and tomorrow.

A combination of tonight and tomorrow both taking place at the same time. A specific time of the night that takes place during just before and after the day rolls over at midnight. For example, you have a workshift that begins at 11pm, you could refer to your workshift as taking place tonighrrow.
