Its pretty simple: first, access the Toribash folder, inside it you will see a folder called 'fonts'.
Once you access it, remove the 'Toribash' file, and get a font from here:
http://www.dafont.com/ (for example). Download and unzip the file you wish, rename it as 'Toribash', and put it in 'fonts' folder.
You can also do it without downloading any fonts. In Fonts folder, theres another file called 'misc', you can copy it, rename it as Toribash and place it in the folder again (deleting the previous Toribash file obviously)
I did it, check the result:
