I have seen threads with abbreviation explanations and was grateful for the help on those I was not able to reason out.
But there is one I keep seeing pop up that I have no clue about. I am sure I will feel childish when I get the answer, but.........
DH?
I think it is used mostly by the women about husbands..........my mind has several ideas for what this could be.......none of which can be printed here. 
Can I be elightened, please?
