Aata Majhi Satakli is a Marathi, idiomatic phrase whose literal meaning is 'now my mind has moved', but the contextual meaning is of course different.
Something like Hindi phrase 'dimag khisakna' or 'dimag chalna', which would literally mean the same, the meaning here is that I am going mad now, so you better not mess with me anymore, like a warning.
The dialog, which was in Singham and is now a song as well in the sequel Singham Returns, was written by Farhad-Sajid, who directed Akshay Kumar's [It's] Entertainment.
