I am going to hashtag ''Mitt Romney for president'', and no i won't press the hashtag-pound key- on my phone, because it doesn't serve any purpose.

The number symbol that people keep putting in front of phrases, like when they are going to do something.
Thank you twitter for starting something stupid like hashtag...
#number is really "number number"

#inmyshoe is really "number in my shoe"
#a is really "number a"

A symbol used excessively on social media platforms. In recent months, hashtags have been verbally used. If you speak in hashtags, you are a hashtagee. Spread the word: STOP USING VERBAL HASHTAGS
Joe: Yo look at that dude over there! He lifts 500!
Bob: Hashtag (#) Lifegoals
Joe: Wow you've gone that low.

A tagging system instagram and twitter use to make one's posts. Usually the hashtag has nothing to do with the pictures.
#nofilter #totallylegit #minecraft #selfie #nohomo #hashtag... (5500 other items hidden. Tap to view.)

When hash smokers get a quote on the price of the amount of hash they're buying from the dealer. it is written on a little tag, much like a price tag and is found at the pickup spot.
