verb/ma.ʁe/
to laugh; to be amused
“J' sais pas pourquoi j' me parle toute seule, pourquoi j' me ris à la gueule ; peut-être que j'aime me marrer.” — I don't know why I'm talking to myself all alone, why I'm laughing in my own face; maybe I like to laugh.
Probably borrowed from Spanish marear (“to get dizzy”), with semantic shift "to get dizzy" > "to be bored" > "to be amused" (via antiphrasis).
