not give a shite (about something)

rude To not care in the slightest (about something or someone); to attach no importance to someone or something. Primarily heard in UK, Ireland. I don't give a shite about making money, I just want to do something with my life that makes life better for others. I haven't given a shite for the show ever since they killed off my favorite character. Do whatever you want, I don't give a shite.
