Sliding sausage
Sliding sausage is the joking expression for a method of eating little sausage with a lot of bread in times of poverty and need . A small or thin slice of sausage on a much larger slice of bread is pushed back a bit after each bite, so that only a small sausage comes out of a large bite of bread, or the sausage slice is pushed as a whole and eaten with the last bite of the bread. Another name for this is eating bread . Both idioms have been recorded in the literature since 1910.
At about the same time, the term pusher butter came up, with a small piece of butter being pushed on a larger piece of bread with the teeth until the last bite.
