As a beginner in English you learn formal English phrases and expressions. But English communication is not only about what you learn in your English books or an English speaking course. English is not always spoken from the textbooks. We all speak a lot of informal English which includes a lot of slang words and expressions, the English that you mostly hear on the streets and among friends and family.
In this English lesson you will learn some crazily interesting slang words and phrases to describe human body parts. I had real fun preparing this lesson. I am sure you would love it and add these slang words in your casual English conversation.
