mouse holing
v.— «You avoid, at all costs, going down the length of streets or going across big wide squares and things like that, and what you is you use the buildings as terrain as though they were hills or something, and typically what you’ll do is you’ll get into a building at one end of the block, and you’ll go from building to building by blowing holes in the walls inside with a process that’s called “mouse holing,” so you don’t have to go in the street, because if you go in the street you’re vulnerable to weapons that have been sighted along the streets.» —“CNN Live Saturday” by Pat Lang CNN May 1, 2004.
