flatbill fuck bois

Guys with short man syndrome, love to talk shit on the internet, wear flatbills and affliction T shirts. They can usefully be found at a drag strip or fast food joint.

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!
