Couple of stoner associations they miss, as the article only really mentions the use of the pokey:
the part of the body, under the gas pedal/wheel part, is completely flat (unlike the rest of the body) to allow for scraping up weed after it has been ground up.
when you turn the lighter upside down, after sparking it, the flame gets considerably bigger for bong rips.
Back in the day when everyone still smoked flower, I would see people do this all the time with their lighter after a couple of hits. Personally I found it much more effective to just use your finger, so that's what I always did instead. It packs down so much better.
