To answer the latter half of your question, no, people will not think you’re cool for doing this. Some will be majorly put off by it. Some miiight not be entirely too cringed out by it, but they still won’t think you’re cool just cuz of this. Your best bet is to be yourself and find the people who think that’s cool, whether that includes talking oldtimey or not.

How old oldtimey are we talking btw? Just out of curiosity lol
