意味

Timeline — an abbreviation of タイムライン, referring to the main feed on Twitter/X or other social media.

TL is the standard abbreviation for タイムライン and is used far more frequently than the full word in casual online communication. Japanese Twitter users commonly describe the state of their TL as if it were a shared neighborhood — saying things like 'TL is rowdy today' or 'my TL is full of cherry blossom photos.' The concept reflects how Japanese users see their curated feed as a communal space shaped by who they follow.
