In colloquial English, the phrase "the fuck" can be added to questions as an intensifier, for example:
- "How the fuck did you do that?" conveys greater confusion than "How did you do that?"
- "Who the fuck is that?" conveys greater hostility than "Who is that?"
I'm already aware of a few phrases, but they seem to be specific to "what" questions:
- ¿Qué carajo están haciendo en mi cama?
How would I do something similar for all questions in Spanish?
