No widely documented origin is attached to this short clip, so it is best understood as an online soundboard phrase rather than a line tied to a single film, game or show. Its appeal comes from the wording itself: crusaders suggests a united group with a shared mission, which makes the phrase easy to reuse across very different videos. Online, short rallying lines like this travel well because they can be dropped into gaming sessions, sports edits, group chats and reaction clips without needing extra context, and that flexibility is why it continues to circulate.
