The Brief: WBK is an acronym for "we been knew."
DEEP DIVE
“We been knew” means “we’ve known it for a long time” or “I told you so.” The term is often associated with African American Vernacular English (AAVE) and black slang.
Online, this phrase and acronym WBK appears to have been popular on Black Twitter before it was adopted on Stan Twitter, specifically on KPOP San Twitter.
