The phrase comes from everyday Rioplatense Spanish, where vos is used instead of tú and arrancamos is often shortened in casual speech. Clips of short spoken lines like this spread mainly as WhatsApp audios and soundboard buttons in Argentina and Uruguay, shared between friends rather than taken from a single famous scene. Its humor depends on local slang and timing, so it travels best in Spanish speaking group chats, streams and edits where everyone already knows the expression and uses it to mark the moment something begins.
