Fossilized Black Americans (FBAs)

A "Pretendian" is a term often used by Indians to describe someone who falsely claims Indigenous ancestry or cultural identity without any legitimate basis. This term is often applied to individuals who disrespectfully appropriate/change Indigenous cultures or traditions for personal gain (in an effort to seem more exotic or interesting than they really are.)

Similar to a “pretendian”, Black Americans have a play on the term "Foundational Black Americans" (FBAs) — "Fossilized Black Americans."

Just like “Pretendians”, Fossilized Black Americans cling to any minuscule amount of African DNA remnant from their ancestors, to try to legitimately claim that they are part of the black identity in the present (Even if authentic, dark-skinned Black Americans don’t see them as black; Even when they don’t look black; Even when they’re extremely distanced from blackness and black culture)

They are fossils of the former identity that their ancestors embodied.

“Yeah sure, they’re ‘FBA' alright – Fossilized Black Americans (FBAs)”

Fossage

Fossage (FEE-kul sah-sij): AKA Fecal Sausage: The technique of making a sausage link like product using a filler and casing; in this case the filler is poop straight from the butthole into a condom as acting as the casing. In most situations the filler will unroll the casing as it’s pushed out. When complete the end can be tied off creating the fossage link, which can then be twisted into multiple smaller links for easier handling.

Billy needed to poop but was stranded in a nice place where he didn’t want to make a mess, with only a condom in his pocket he decided to make a fossage link and throw it in the trash.
