"And a point will be taken from Gryffindor House for your cheek, Potter."
- Snape to Harry (PS8)
"He cheeked me."
- Dudley to Harry, speaking of Mark Evans (OP1)
"Lily Evans. One of the brightest I ever taught. Vivacious, you know. Charming girl. I used to tell her she ought to have been in my House. Very cheeky answers I used to get back too." (HBP4)
“Cheek” means “insolence”, so “cheeked” is “sassed, bad-mouthed”.
