删除仅与其他列中的一个值相关的行pandas

想象我有这样的数据框：

item     name     gender
banana   tom      male
banana   kate     female
apple    kate     female
kiwi     jim      male
apple    tom      male
banana   kimmy    female
kiwi     kate     female
banana   tom      male

有什么方法可以删除该人仅关联（购买）少于 2 个项目的行？我也不想删除重复项。所以我想要的输出是这样的：

item     name     gender
banana   tom      male
banana   kate     female
apple    kate     female
apple    tom      male
kiwi     kate     female
banana   tom      male
