throw oneself at someone's feet 这个俗语和我们所说的“拜倒……的石榴裙下”有异曲同工之妙。公开对某人表示爱慕。

【例句】
I'm still looking for the right girl to marry. And when I find her, I'll throw myself at her feet and ask her to spend the rest of her life with me.
我现在还在物色一个我认为合适的女孩作为我的妻子。一旦我找到了，我就要拜倒在她的石榴裙下，恳求她作为我的终身伴侣。

As soon as he met her, he threw himself at her feet.
他一见到她, 就拜倒在她脚下。
