English speakers: Help me!
I'm watching Even Stevens on TV (you know these series?)
I don't understand this sentence
:Younger men are totally in this year.
Here is the dialogue:
When did you realize you had a crush on Louis?
Well, yesterday, when I was leaving your house...
Ruby, come on. You're a year older than Louis. You're in different grades.
Younger men are totally in this year
. I have so much to teach him.
Louis is Ren's younger brother. What does Ruby mean when she said that?
thank you so much
