Get over it…there's no shame in finishing your words with "ing"…saying the "g".
You might even sound smart!
This is a meatball aberration.
When our favorite TV cooks and chefs talk about preparing meatballs, they usually tell us to brown the meatballs "on all sides."
But meatballs are round; they don't have sides. They just have an OUTSIDE…a surface. Or maybe the sides are very, very small; so small we can't see them.
Another fairly useless expression!
Commentators in sports, business, and news have come to use this expression when it's not even necessary. Whenever they're talking about future matters, "going forward" — or "going fuhward" as some say — is obvious; so the expression has become a pseudo-elitist type of redundant phraseology.
