"copypasta" isn't super appreciated here. At best it's a homophone of a word that is ableist. At worst, people are actively being ableist. You never know with the internet, we have a ton of extremely problematic people pop in and use words that mean the second option. There's just better ways to express disbelief or calling someone socially inept.

But yeah, prude.

Lame, sucks, bad, etc. They all mean the same thing, essentially.

There is absolutely nothing ableist about using lame. Nobody uses it to mean impotent or unable.
