DH=Dear Husband
or
DH=Down Hill
depending on context
so...your DH could be heading DH really fast if he starts misbehaving!!
or in my case since mine is now as ex:
DH=D*** Head (this is a family board but I'm sure you can fill in the blanks!)
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
