A smile that knows something you don't, and wants you to notice.

means A smug, self-satisfied half-smile that signals pleasure, superiority, or private amusement rather than warmth.

from Smirk descends from Old English 'smearcian,' meaning simply 'to smile.' It's a distant cousin of 'smile' itself — both likely trace back to the same ancient root — but somewhere along the way 'smirk' curdled, picking up its smug, self-satisfied edge while plain 'smile' stayed innocent. So the word didn't start sly; it got that way.
