Hashtag and the her too's 

A way to mock the overused #metoo movement, mostly used by libtard feminists who consider even a simple compliment by a white male as harassment.

Damn, I gave Katie a compliment about how nice her new sneakers looked and she flipped out on me and said I was harassing her. I bet she took to Twitter and Facebook to join the hashtag and the her too's.

Hashtaggot 

One who makes a fool of themselves by going and using the symbol "#" in front of a jumbled mess of words to make it a sentence, or uses the actual word "Hashtag" on a social network that is not twitter.

Rebecca: "OH MY GOD #FOLLOWMEONINSTAGRAM #SWAGSWAGSWAG"
Joey: "Wow, you're such a hashtaggot"

Hashtag Abuse 

When anyone uses a hashtag (simply a way for people to search for tweets that have a common topic and to begin a conversation) on a website, text message, or anything that does not pertain to Twitter. This is quite annoying considering hashtagging only works on Twitter.

(In a text message)

Guy: Hey want to go see Paranormal Activity 3?
Girl: I can't, I have to work :( #IHateMyJob
Guy: That doesn't work on text messages, only Twitter.
Girl: But I do it on Facebook all the time! #FreakingOut
Guy: Oh my God you're an idiot.

She is a Hashtag Abuser
