Thanks. I did look up "meh" on duckduckgo, and saw something about an "impulse buy" (meh.com), then wondered what is added by using these neologisms. Now I see that the third result for each of these words is from urbandictionary.com, and those definitions comport exactly with yours. Every written human language has a vernacular versus a written form, typically with a cline between them. English is the closest in correspondence between the two, among the languages I know, but the difference remains. I do read English every day, but it is much slower for me when people use neologisms that don't have germanic, greek, or roman antecedents, as most English words do. I don't mind learning new vocabulary, especially when it is more precise or apt, as is often the case in math, philosophy, art, or in technical works. The neologisms this author chose to use are interjections, and I still don't see what power was added to his prose by their use. I suppose they act as shibboleths, signalling his class identity in some way. The entries on urbandictionary.com do give a clue: the origins appear to be "Bill Cosby", "The Simpsons" and "South Park". The OP likes comedy and cartoons? Or marijuana? It's common to hear people talking about getting stoned and watching "The Simpsons" or "South Park" all day. And, that may partially explain his inability to debug his code. Thanks again.
