To 'kowtow' is to kneel and touch your forehead to the ground as a sign of deep respect or submission. It's a gesture of extreme deference, historically practiced in China. Think of it as a super-bow. It indicates subordination or obedience to someone in authority. Nowadays, 'kowtow' can also mean to be excessively servile or obsequious. It's like fawning over someone to gain their favor. While less common as a physical act, the word still carries a strong connotation of subservience.
