У неё горели глаза, горели щёки, волосы летали над плечами, и чёрт был ей не брат (Стругацкие 1). In the center of the circle Diana was engaged in a wild dance with the sallow-faced fop, the owner of the eagle's profile.

"Ну что ж, позовём Брегмана, отпетого старика, - решил, наконец, Феоктистов. - Ему сам чёрт не брат" (Паустовский 1). Feoktistov sat for a long time pondering as to which of the drivers in Belaya Tserkov was indeed the most reckless. ..."Well, why not-let's call Bregman, the old rascal," Feoktistov decided at last. "He'd take on the devil himself" (1a).
