stuff up
v. phr.— «The Singing Budgie’s incapacitation left hoteliers doing the locomotion to move hundreds of rooms at short notice, and Wotif obliged. Wood says Wotif will be hard to dislodge from its dominant position unless it “stuffs up.” “Stuffing up”—excuse the technical jargon—means diversifying into activities such as buying travel agents.» —“Room at the inn proves comfy” by Tim Boreham The Australian (Sydney, Australia) June 6, 2006.
