Chiefly in representations of regional speech: a tomato, especially of a small round variety.
Particularly associated with the southern and south Midland United States. Now also (in form Tommy Toe) used as the name of a particular heirloom variety of tomato bred in the Ozark mountains and popular in Australia.
Mid 19th century; earliest use found in Operative. Alteration (either humorous or folk-etymological) of tomato after the male forename Tommy and toe.
