stuck on silly ideas 'cause it's all you can cook
It's a quote from a British rap song. I understand that "cook" here means "do" or "think of", am I right?
The aspect which interests me the most here is: what group in the UK uses this word? What does it tell about me if I use this word? (For example about my age, my music taste etc.)
Please, provide two more examples of usage of this word.
