Be sure to follow the rule before you head out.
Rule: You must post before you leave.
Yeah, I don't think I've ever seen someone use the old definition of lame unless they were being intentionally antiquated, and even then, never in a way to put someone down.
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.
