Perhaps I used the wrong term. I mean putting in a big bet where your opponent figures to rarely be able to call a big bet.

Also, I think this mostly applies to higher buy-in games where your opponents have adapted well to deepish stack play and know how to put you into difficult spots for your stack. By buying in short you can catch them making 100+ deep plays when you've changed the game to 50ish on them. You also make it harder to push you around because you can just commit when you have a pretty good hand on the flop or turn, then throw in an occasional all-in bluff back that they can't do much about without lots of outs or some showdown value.
