louse up

I didn’t want to louse up the photo opportunity because it was the only chance to get the picture we all wanted, Clinton and Assad.

The winter storm bearing down on the region and most of the East Coast on Wednesday louses up plans for everyone but those who planned to sit at home in a rocker by the fireplace.

In either instance, it louses up my request.

I’m aware of it, still don’t use it, and yet I’ve yet to lose or corrupt any data or louse up the file system of a storage device.

I said okay, I didn't want to louse up the deal over a little thing like that.
