Hashtag-Imbecile

A person who hashtags words or phrases that are extremely irrelevant to the post. Making them annoying as fuck.

Tom: Have you seen Patrick's picture of his cat?

Patrick's Instagram: Picture of his cat on a couch.
#Chevrolet #coffee #chair

Eric: Yes I have. But what do his hashtags have to do with his cat?

Tom: I don't know. He's a hashtag-imbecile.
