Moat-and-bailey
I don't normally point out typos (and it's probably better on balance for LW not to be the sort of nitpicky place where everyone does) but this one is (1) almost exactly backwards and (2) sufficiently plausible-sounding to be dangerous :-). It's motte and bailey. The motte is the raised mound with a fortification on it. The moat is the big ditch around the castle, usually filled with water.
The bailiffs got drunk on Baileys, crossed the moat, and demolished the motte leaving nothing but bay leaves and motes of dust floating in the air...
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
