limped pot, trip queens

[bi11 frist]

i was totally lost this hand. his line is so retarded that it has to be either super strong or complete air right?
in retrospect if i think im beat, i should fold turn, but the double check-min-raise just froze me and i called. i still have no idea what he had. any thoughts?
