This word was also new to me when I joined this forum. I've assumed Tank means a full weight Scottish kilt but maybe some of the longer serving forumites can confirm this. Another of the in phrases used by established members of the forum which doesn't make much sense to some of us on the east shore of the Atlantic is Jones. Is this the name of a kiltmaker and does Jonesing have something to do with wanting to wearing a kilt of that make?
