graze

Cows graze on grass people graze on snacks and finger-foods, like when you keep grabbing a handful of chips every time you pass by the table at a get-together.

Graze means "to feed on grass" as sheep, horses, cows, do in a meadow — they eat a little at a time, but constantly. People sometimes graze too, munching on small snacks all day long instead of having a real meal. It also means “to touch lightly,” like when I pitch a baseball to you — and I accidentally hit your arm. With luck, the ball only grazed you, meaning you aren't hurt at all.
