@SallyStrange Pronouncing just the first syllable or two of a multi-syllabic word – "sitch" for situation, etc. As long as it still makes sense, Y not.
Casual writing in sentence fragments instead of gramatically correct sentences = fine as long as it's understandable.
Oxford comma only if needed for understandability. And it's ok to pronounce some non words as words ("lol" said as a word).
I've always flung words around idiosyncratically, and anyway language is a living, morphing thing imo!
