Please help me explain what eating grapes means.

Eating grapes means eating grapes in your mouth.

Grapes, also known as raisins, are common plants of the genus Vitis. Deciduous lianas with slender brown branches. Subcircular simple leaves alternate, nearly entire to 3-7-lobed, and the leaf margin is serrated. Multiple buds are inserted in leaf axils. Tendrils or inflorescences are opposite to leaves.

Five petals, connected at the top and separated at the base, fall off in a hat shape when flowering. Berries are mostly round or oval, with turquoise, purple black, purple red, etc., and fruit powder.
