Lol(l)

When I was growing up it meant:
...to hang droop or dangle
...to sit, stand, or lie in a relaxed position
...if your tongue or your head lolls, it hangs down in an uncontrolled way

Now I'm more likely to use it meaning:
...Laugh Out Loud (Literally)
...Lots of Love

These dogs are doing it the first way....
