That is absolutely true in that any, at least any non-profane, word can be used as a phonetic. However, readily recognizable words definitely work better. That is why there are standard phonetic alphabets including the ICAO and APCO. In the world of working DX geographical names have become a defacto standard phonetic alphabet.
Now when working your friends on a local FM repeater, then "funny phonetics" are fine since they know who you are.
The late Jack Camp, W5HS, used to say "Whiskey Five Horse . . . . . . Shoe" when working locals. But, when he was working DX he used "Washington Five Honolulu Spain".
