Jan, thanks for dropping by my site. Excellent question, by the way.
Yes, people do make up words and because most of us use the internet, we get to see all kinds of weird and wonderful word creations.
Some make me laugh.
Some make me cringe.
Some make me gasp in horror :-)

The best way to find out if a word you want to write is ‘real’ or not, is to check a dictionary.
Please also note that dictionaries differ in English-speaking countries, so a word which is acceptable in the US might not be acceptable in Australia or the UK.
If you have any examples, let me know and I’ll share them here.
