verb (old military).—Grose says ‘a military term used by the private soldiers, signifying a solemn vow or resolution not to get drunk for a certain time; or, as the term is, till their CAGG is out, which vow is commonly observed with the strictest exactness: e.g., “I have CAGG’D myself for six months. Excuse me this time, and I will CAGG myself for a year.” Common in Scotland, where the vow is performed with divers ceremonies.’
