When used the right way, "Call it a hunch...," is a good way to preface a sarcastic remark.
One recent example: I kept an eye on my cat, Collette, while she sat on the table as I ate. When I looked away, however, she bit me on the arm. While I exclaimed, "Ouch!," Collette scampered into the living room and hid under the end table.
"Call it a hunch," I told her, "but I think you know you've done something wrong."
