2 idioms that use the word HIGHWAY
Highway robbery = Prices that are very expensive (too expensive).
“$9.00 for a cup of coffee!? That’s highway robbery!”
My way or the highway = Do something the way I say (my way) or leave. There is no choice but to do it the way I say.
“I told my Dad that I don’t want to rake the leaves this weekend, I want to go camping with my friends. He said as long as I live in his house it’s his way or the highway.”
Remember that music is great for vocabulary but the grammar is often strange! In this song ‘imma‘ is a contraction of ‘I’m going to.” Enjoy!
