A Tumblr GF is a girlfriend that you have relations with on the popular blogging website tumblr.com . They are generally very needy and need you to be on 24/7 because they have no life and only care about you. When you get a Tumblr GF, you know you're going to die alone. If you have had a Tumblr GF, please refrain from telling anyone about this horrible part of your past.

Person A: ..yeah, I'm gunna have to go... see you never.
