"随便吃"在英语中叫做 "grazing"。这个词的来源可以追溯到中世纪，当时它用来描述牛羊等家畜在田野上放牧。在现代，它被用来描述人们在进餐时随意地吃东西，而不是在正餐时间进餐。
例句：
I'm not really hungry, I'm just grazing. (我并不非常饿，我只是随便吃吃。)
I've been grazing all day, I really need to sit down and eat a proper meal. (我整天都在随便吃，我真的需要坐下来吃一顿正餐。)
My coworker is always grazing at her desk, no wonder she never loses weight. (我的同事总是在办公桌旁随便吃，难怪她从不减肥。)
