Sometimes you worry that sitting in a dark room all day watching films is bad for your brain. But I'm a firm believer that you can learn AND watch movies at the same time. Fortunately, Dwayne "The Rock" Johnson agrees with me, as you can see by his use of the word "emasculating" in the middle of the Journey 2 The Mysterious Island trailer.

What does emasculating mean? How do you use it in a sentence? The Rock reveals the range of his vocabulary...

Word: Emasculating

Definition: "To make (a person, idea, or piece of legislation) weaker or less effective."

As spoken by: Dwayne Johnson

In: Journey 2 The Mysterious Island

Journey 2 The Mysterious Island is out on Friday 3rd February. Read on for some pretty new character banners - including one featuring Michael Caine riding a giant bumblebee. Yes, really.
