The term used by our favorite SM in his most recent post isn't even found in Merriam Webster, nor does Google deliver unambiguous references. Can any native speaker please help in interpreting what he wrote? My command of that language obviously doesn't suffice, so please KISS. Thanks in advance.

Four questions Walter:

1. What is an SM?
2. What is the term?
3. What is "that language"?
4. Why is this posted in a new thread?
