Chienlit is a traditional French term typically translated as masquerade (French Mascarade) or carnival/chaos. It was brought to notoriety by General Charles de Gaulle in an angry speech during the student protests in Paris during May 1968 in France, when he used the vernacular term as a scatological pun "La réforme oui, la chie-en-lit non" meaning Reform yes, but chaos - no whilst the pun was Reform - yes, shit in bed - no .
The term is now common parlance in French political commentary, used both critically and ironically referring back to de Gaulle.
