I have watched lefts use this troll, and people always fall for it. I think it is an interesting and not-widely-known rhetorical technique, and maybe folks here can use it in different circumstances.

>1) what is an sjw?
>2) [someone explains]
>3) what? are you serious? that's SO stupid lol!!!!!
Its purpose is to humiliate the ideas behind the term in a way that appears unbiased.
The best way to defuse this troll attempt is to ask someone if they are trolling BEFORE someone takes the b8. Do not chimp out about it, and do not answer their question (let someone else answer, if they want). When leftytroll is forced to confirm that they are not trolling, their response in Step 3 MUST be subdued, lest it expose them as a liar.
Some ideas for lefty terms to use with this template:
>poz / pozi
>twinspirit
>glass ceiling
bump for exposure
