I think it’s just part of how languages work and people communicate, at least for people learning a second language - but I even do it in my native tongue, so I think it’s general.

For example, if when you are learning English you hear a lot of people say “God dammit” when they are frustrated, then when you are frustrated you’ll probably also start saying the same without ever even thinking about God. It’s essentially just a series of sounds when you learned to make to express frustration.
