Haut les Coeurs is a familiar French expression meaning take heart or keep your spirits up, and the IG2I tag in the clip title connects this version to that school community. Short rallying cries like this travel well on soundboards because they are instantly recognisable even to listeners who do not speak French, and the upbeat delivery gives them a second life in student videos and memes. It remains useful because encouragement never really dates, and a short cheer fits neatly between jokes, highlights and outros.
