Angie, you are correct about those acronyms. Around here, I refer to my mate as HH (handy husband) because he is very clever with fixing and building things. Most people refer to their spouses as DH (dear husband) or dear wife (dw). One of our members, Constance, has been using HB for her spouse, and I have been meaning to ask her what that means.
