flat porn

Flat porn is visual pornography that is flat in nature, like a regular static image (think Tumbler or old school photos). It is not available in a 3D, interactive, or virtual (think Occulus) way.

My husband is not allowed to watch virtual porn, flat porn is fine because there is no depth or interaction with it!

Flat Brimmer

Someone that's into "extreme" sports such as down hill mtn. biking, BMX, motocross or anything that you can get "rad" with. A flat brimmer will wear a ball cap with a flat brim with Oakley sunglasses and can usually be seen drinking a Monster Energy drink. A flat brimmer will think he or she is better than the rest and loves to pose for photographs.

Did you see that flat brimmer with the Fox jersey acting like a douche to those other riders?
