Another dialect that you might encounter online is African-American Vernacular English (usually shortened to AAVE). A lot of the internet buzzwords of 2016 derive directly from AAVE. Here’s a short list: lit (e.g. “the party is lit” – it’s great), bae (boyfriend/girlfriend etc.), woke (aware of political realities), on fleek (flawlessly styled), shade (specifically “throwing shade” – delivering a put-down, usually to someone who deserves it), squad (your friends), realness (as the word implies, being authentic), slay (to succeed in something really difficult) and basic (enjoying unsophisticated things).
But many of these words have appeared through their usage on the internet by AAVE speakers, where they have been borrowed by people who may otherwise have had no experience of AAVE. Standard English has always been inclined to borrow from other languages and dialects, and their use on the internet makes the whole process quicker and easier.
