Snack : A snack is a quick and basic meal, usually made up of pain, cheese or delicatessen.
In colloquial language, "to have a snack" (or, even more slang "la seed "), It is" to eat on the go ", that is to say to carve its slice de pain au couteau and garnish it with ham, rillettes, sausage or camembert.
A snack-bar tradition has won its letters of nobility: the machon lyonnais.
The word "snack" originally designated a tool that toothless old people used to break the crust du pain.
