Saucy is cheeky but usually with a "naughty" (as in sexy) undertone, but not always.
You could say that a young child had a saucy grin, they might have done a poo in their fathers hat and then have a saucy grin like they know its wrong but they find it funny.
Or a little girl who has dressed up in her mothers clothes might walk around the street trying to walk in her mothers high heels and make up splattered all over her face, she is being saucy an old lady would say.
Carry on films, OOH SAUCY.
NOT DRUNK etc.
If a woman says something suggestion in an innuendo or doo blon tondra way you would say "OOOOH Saucy", it means naughty, cheeky.
