To give a woman a good fucking.
Used by Artie Piscano during the grocery store back room scene of Casino.

PISCANO: I was out there with my cumma.
BORELLI: Your cumma? What are you doin' with your cumma?
PISCANO: What else? I gave her a schaff.

This girl is a music sensation. Crossed between a mix of Hayley Williams and Taylor Swift. She has hits such as "You Are Here," "Alibis," "The Line," "Disarray," and "Keeping Secrets," as well as many more. She is played on the radio. She is gorgeous and extremely talented at singing, playing guitar, and writing songs. She is a star and my idol.
