It is the same thing as scarfing something down, except it is British.

它跟狼吞虎咽是个意思，只不过是英式说法。

I took my food with me, scarfing it down as I got his dinner. It burned my tongue.

我拿着盘，给他弄晚餐，狼吞虎咽地把面条吃完。我舌头被烫到了。

Okay, look. Mommy needs to lose a few pounds, and it's not easy eating healthy with you two in front of me, scarfing down all the good stuff.

好，看着我，妈妈需要减肥，跟你们两个起吃健康食品对我来说很不容易，赶快把这些美食吃光吧。
