divulgâcher

to spoil (by revealing information prematurely)

“– Tu as l'air bizarre. À quoi tu penses ? – Au cirque. – C'était comment ? – Génial. Pas impossible que je laisse tomber le journalisme pour devenir dompteur... Tu liras tout, demain matin, dans mon papier. – Jamais de la vie ! Je vais pas me divulgâcher le plaisir du spectacle, comme ils disent au pays des castors.” — "You have an odd look about you. What are you thinking about?" "The circus." "How was it?" "Great. I might give up journalism and become an animal tamer... You'll read all about it tomorrow morning in my article." "Never! I'm not going to spoil my enjoyment of the show – divulgâcher, as they say in Quebec."

Blend of divulguer + gâcher.
