The clip comes from Titanfall 2, the 2016 sci-fi shooter from Respawn Entertainment whose campaign dialogue has supplied soundboards with quotes for years. Short, quotable voice lines travel well: this one was ripped, uploaded, and passed around gaming communities as a shorthand for withholding information. It sits in the same family as other game callouts like Enemy Spotted and bomb has been planted, the kind of instantly recognisable voice line that needs no context to land in an edit.
