Otivame na kupon translates from Bulgarian as we are going to a party, and that literal meaning is the whole joke behind its spread online. Bulgarian speakers share the clip in group chats and short videos whenever plans suddenly turn social, and the phrase has travelled beyond its language because the excited delivery is clear without translation. It is now used as a reusable reaction for travel clips, pre party montages and ironic celebrations where a small plan is treated like a major event.
