So you think “Big Tilde Ten” is the best way to say it? Maybe you should throw another tilde underneath that one to make it an “approximate” symbol. That might make your point a little more sensible ;)
In English it is sometimes used to represent approximation, for example ~10 would mean “approximately 10”. Similar symbols are used in mathematics, such as in π ≈ 3.14, “π is about equal to 3.14”. Since the double-tilde (≈) is generally not available from the keyboard, the tilde (~) has become a substitute for use in typed entry.
And as you know, I’ve been typing for four decades, occasionally well.
