I have two characters who code-switch. That inspired me to try and learn more languages so that I too, can do that. Currently, I use "wo" for "where" all the time because its shorter to write. I'll also add in Hebrew here and there, but I wouldn't call me a code-switcher yet per se, because it's more of a cultural need to switch to Hebrew, and I don't add in enough German, or add in other languages yet. I will though, before years end.
