What does a Twink character mean?

[Xanhast]

I keep reading about building a Twink character. What does that mean and how is it helpful?

[Cashews]

Its a low level character that is built for low level PVP. Building a good one is usually quite expensive.

Ahh. Thanks.

I have probably about 700-800k worth in my lvl 5.
