hashtagslag 

A male or female user of social media, mainly Twitter, who uses hashtag in an inappropriate way. One or more of the following characteristics will need to be present:-

1. Using 5 or more hashtags in one tweet;

2. Hashtagging something that is so long or random, there is no chance of it ever trending (eg. #havingamediterraneanpastabakewiththemanofmydreams);

3. Using "#nofilter", even when they have put an effect on or edited the photo;

4. Tweeting with hashtags at least 3 times an hour about:-

a) usual tasks or household chores; and/or

b) their pets (eg. My chihuahua just did a whoopsie behind the sofa #smellydog #ilovemyrat)

5. Saying the word "hashtag" before phrases in face to face conversations.

The more of these characteristics that are present, then the more hashtagslaggy, the hashtagslag is.

Tarquin: Have you seen Seb's girlfriends latest tweet?

Frances: No, what has that hashtagslag been hashtagging now?

Tarquin: She obvs. out with Seb. She's said:-

"Out with Seb for a meal, his treat #nandos #piripiri #canwaittostuffmyfacewithmachospeas #feelingblessed #sohappy #lovemyman"

Frances: Man, she is such a major league hashtagslag!

hashtagasm

Any social media post with more-than-five hashtagged items, especially a collection of unrelated ones. #this #that #theother #random #etc and so on.

Too many of my friends' posts end with their latest hashtagasm.

hashtaghashtag 

When you are too mainstream for the normal hashtag and wish to break the mould and become an edgy hip*

"I saw your tweet last night, my mind was blown"
"You saw my new thing?"
"Yeah!"
"I was banterful, 'My dogs just squat everywhere #hashtaghashtag #bitgrim #nomorefibrefor them'"
"Why you so witty?"
"I know not"

hashtagram 

Like Instagram, this site should be made. But posts should contain hashtags.

"Hey, can I get your hashtagram?"

hashtagfuckwit 

Refers to people who are so fucking narcissistic that they hashtag every element of every selfie/photo/status update they post ANYWHERE. The hashtags are totally pointless, annoying as fuck and make you want to punch a wall.

Sarah: "Just took a pic of this dandelion. Should I put my water bottle in front of it so it looks more natural? And sit them on my book? Then hashtag myself, my website, my unborn children and all my qualities?"
Matt: "no you hashtagfuckwit".
