manger la puck

to selfishly keep all the attention on oneself

Comes from hockey, where a player who won't pass and keeps the puck to themselves is said to be eating it, used more broadly for anyone who hogs the spotlight or the credit.

Il mange toujours la puck dans les réunions, personne d'autre n'a la chance de parler.

He always hogs the spotlight in meetings, nobody else gets a chance to speak.

Wiktionary marks the etymology as incomplete, but its senses trace a path: first taking a puck to the face, then hanging onto it instead of passing to a teammate, and from there to hogging the limelight well away from the rink.
