A vegetarian or (less commonly) one who eats only leaves.
My friend Shilpa is a crazy feeterbuster. She is practically a giraffe and only eats iceberg lettuce!
A vegetarian who busts feet (they are very common). They placidly eat many leaves and resemble a giraffe in their eating habits. Feeterbusters are generally well-liked in their communities.
Shilpa eats so many leaves! What a feeterbuster!
