So now I'm going to give you three slang expressions you can use at the movies.
First, two thumbs up, which means the movie is very very good. I give the new Harry Potter movie two thumbs up.
Next, a bomb, which means the movie was terrible. I would not go see the new commonly film. It was a bomb.
And last, sold out, which means there are no tickets left. For example, we got to the movie theatre late and it was sold out.
So those are three slang expressions you can use at the movies.
总结：
1、give ... two thumbs up 认为...非常棒
e.g: The project was finally given two thumbs up. 这个项目最后被认为非常棒。
2、bomb 不成功的、非常差的戏剧、电影或事件
e.g: This is just another one of Hollywood's bland and boring bombs. 这只是另外一个好莱坞乏味无趣的不成功的电影罢了。
3、be sold out 售光，卖完
e.g: Tonight's performance is completely sold out. 今晚表演的票全部卖光了。
