R-slurred

Phillip called my friend "r-slurred" yesterday.

whether the conclusion is prima facie r-slurred does indeed have an effect on how people respond to it, let this be a lesson to you

That's probably still semantically wrong but at least it's not an entirely r-slurred argument.

you know that children's book with the r-slurred little bird that looks for its mother and asks like, a pig a cow a construction crane etc. if it's its mother?
