“Did he give me a khmalye!” (NJY)

"When I grew up the term khmalye was a form of physical violence on a
person. A knip was a pinch, a frask was a forehand blow to the face, a
patsh was a smack of any small sort, and a khmalye was best described as an
uppercut." (source)

"Mr. Portnoy also lists many more terms one could use, such as a knak (a crack, a blow with the knuckles); a knal (a lash like that of a whip); a trask (a good box); a khmalye (a thrashing); a bentsh in kop (literally, a 'blessing on the head'), that is, a smash on the head with a piece of wood, and so on."
