A hashtag (#) is used most commonly in tweets to signify that you have autism.
Dana: "#swag"
Me: "I can't write hashtags on my keyboard so I'm same from this cancer. By the way, swag means secretly we are gay."
Dana: "I said #SWAG"
Me: "Alright, good to know that you're gay too."
Dana: "Wait what"

A scent that the Tag Fragrance Company(A division of Proctor & Gamble) attempted to market to the "stoners" or "potheads" in the western part of the United States and Southwest Canada. The market research focus groups took place in three cities, Seattle, San Francisco, and British Columbia. It seemed to be going well during the initial phases of the tests. Everybody loved how it smelled "earthy and sweet" at first, but did not like however, that after a few minutes, there was a "noticeable, underlying funk that just wouldn't wash off or go away."(Much like the members of these groups and the couches that they happened to be staying on at the time. Respectively.) They did try to overcome that hurdle by adding patchouli oil to the concoction, but found it only temporarily masked the stench. The Tag Fragrance Company and Proctor & Gamble, at the advisement of their corporate lawyers, ultimately decided against the release of Hashtag when the test subjects were caught deliberately concentrating, then inhaling the contents of the spray cans out of giant balloons in an effort to "catch a free buzz".
"Uh, dude..... If they sell hashtag at the co-op or natural market you go to, let me know and... uh, what was i saying bro?
