A person who online or in email, has the courage to say things that he/she wouldn't have the courage to say in real life.
Bob has a lot of ecourage with the mean and degrading things he says online and in emails, but in person he is quiet and unconfrontational.
When someone will send flirty emails and texts, acting like they are interested in you, but when you hang out in person they act all nonchalant and never indicate they are interested in you.
I went out to the movies with that guy last weekend but he never tried to make a move or anything. But then, when I was driving home, he sent me a text talking about how great I am and how much he likes me. Why do I keep meeting guys who only have eCourage??
