吃货food junkie嘴馋。

老外常用craving来表示馋：

I have a craving for ice cream. 我好想吃冰激凌。这里craving是作名词。

I‘m craving cookies. 我好想吃曲奇饼。这里craving是动词加-ing。

craving有渴望的意思：We often crave what we can't have. 我们经常渴望我们得不到的东西。

crave通常做及物动词。crave something可相当于have a craving for，所以动词crave后通常不用再加for：

Many young children crave attention. 许多小孩子渴望得到关注。

试比较这两句：Are you craving anything right now? I have a craving for chocolate.
