twittertalk 

When someone posts a reply to you in any given situation, using the @ symbol in front of your name. Can be annoying, when not necessary.

Twittertalia 

The members of the Hetalia fandom that have made twitter accounts to roleplay as certain characters. It's mostly crack roleplay but you do get the rare serious roleplayer as well.

The #worldtweeting on twittertalia accomplished nothing.

Those twittertalia roleplayers are weird

Twittertainment 

First coined by Twitter user @H0llywoodWh0re to describe entertainment though the public content on Twitter.

Health care plan? How about free health care on Twitter for the fuckwits.. until I guess Tweepies will have quality 'Twittertainment'.

He's my Twittertainment since he decided moronic fuckwit was his new day job.

Quality Twittertainment, I love how the current events tend to arrive earlier though Twitter.

@H0llywoodWh0re, follow her because she's open, opinionated, and she's a 'Twittertainment' Twitter addict.

twittertariat 

Those ranks of users whose comments go largely unnoticed by the world outside twitter. Below the twitterati but, of course, above the lumpentwittertariat.

No one reads my tweets - I'm a card-carrying member of the twittertariat.

Twittertard 

A Twittertard is someone who cannot decipher Twitter code or blemishes it with their idiocy.

If you have trouble with @, # or cannot say anything constructive, you may be a Twittertard.
