What is a sass account? (on twitter)?

[Christina Smith]

I'm a little confused as to what a sass account is on twitter? Please don't answer with "an account with sass" because that honestly doesn't help me haha. If you can't explain, can you name a few sass accounts and maybe I'll get an idea? Thanks (:

Lol okay so do you mean the one direction sass accounts? um they are just accounts that are very funny and dont care if they use proper grammar or capitalization. they also have weird icons and names sometimes. they are very sassy but probably the funniest people i have seen.
Some accounts are:
@gaystagram
@tomlinjuice
@tommospurse
@haylouis
@screwingniall
^^ just to name some.
idek if there is any in other fandoms but who knows lol.
