To party hard, to go on a binge, to paint the town red. Classic, somewhat old-school but still widely used verb that describes throwing a massive, lively party, spending lots of money, and drinking heavily over a period of time (они всю ночь кутили в ресторане — “they were partying hard in the restaurant all night long”).
Нельзя летом скучать, летом нужно кутить.
You should not get bored in the summertime, summer’s there to party.
