A U.S. Army term for a person who will point out how fucked up your boots and uniform are. But in contrast their uniform and boots are worse than yours. This type of person is either a supervisor or a peer. Often associated with spot light rangers.
Hey man where the hell are you going we are supposed to be in the motorpool. Well the boot weasel caught me at the gate this morning and pointed out in front of the Sergeant Major that my boots were fucked up. So now I have to go to Mount Olympus this afternoon to show him that I am really squared away. Well it sounds to me that the boot weasel pulled out his ball bag musket and put his balls in your mouth. No man it felt like doing the hamstring stretch standing while someone put their vein laden meat pipe in my ass.
