Flattie

A breast cancer survivor that is FLAT after a mastectomy. It can be a double or single mastectomy, a survivor or previvor.

It can be because they chose not to get implants immediately or because they had to have their implants removed for one reason or another. An example of why they had them removed, they made them sick.

A friend just got diagnosed with breast cancer and said she wasn’t getting implants. I told her she would have to come with me to a Flatties meet up.

Flatliner

When you’re fucking a diabetic so hard her insulin pump fails sending her into insulin shock only to be revived by cumming in her mouth.

Hey Tina. I hope your glucose levels are in check or else we might have a flatliner.

Flattie

Flattie - a breast cancer survivor who has had one or both breasts removed and chose to be flat. Aesthetic flat closure may also be done after removal of a breast implant that was used to restore breast shape. During an aesthetic flat closure, extra skin, fat, and other tissue in the breast area are removed. The remaining tissue is then tightened and smoothed out so that the chest wall appears flat.

This breast cancer warrior is a Flattie.

Emotional Flatliner

Someone who shows no emotional response to anything, no matter how poignant or stirring. They’re either so repressed that nothing gets through their emotional firewall, or so disconnected from their feelings that even a child’s laugh, a heartfelt poem, a soulful song, or a breathtaking view leaves them completely unmoved. Picture a human equivalent of a flatline on an emotional EKG—zero reaction, just a blank stare.

"I played her my favorite song, the one that makes everyone cry, and she just shrugged—total Emotional Flatliner."
