Sinistralism

prejudice, discrimination, or antagonism by an individual, community, or institution against a person or people on the basis of their cerebral lateralization, or left-handed and including mixed-handed individuals.
Society through Higher Education exhibits sinistralism by not screening left and mixed handed students for communication related learning disabilities which hinder their graduation rates and therefore socioeconomically disadvantaging that minority group.

sinistry

Noun: A ministry of sinners... or a ministry of sin, (or of sin itself).

Noun: A clothing company started in June 6th, 2006.
( Sinistry Clothing is the company that coined the term Sinistry)
We are all born into the flesh, making us all sinners... The bible says that it is a sin to be born into the flesh... Therefore, we are ALL members of the Sinistry.

ALSO: Members of Sinistry have the same beliefs as the great Russian philosopher Grigori Efimovich Rasputin who believed that we should enjoy the pleasures of the flesh, as well as the physical world, unlike the beliefs of christianity as where one is supposed to abstain from physical pleasures.

Bend Sinister

A heraldic convention (a line moving from bottom left to upper right corner) that illustrated bastardy. "Illegitimate" heirs could display their father's crest (like "legitimate" ones) but with an appended "bend sinister."
The "bend sinister" shown in the photo indicates that the bearer of this crest was a bastard of Lord Kent.

sinister D

A situation where a smallish, dried out, extraordinarily tenacious remnant of fecal matter which, when unwittingly rolled into a mixture with toilet paper lint by the action of wiping, becomes almost irremovably entangled among ones anal hair, which in turn causes what one can only refer to as a net of hair that blocks the passage of poop from anus to toilet, leaving a heaping mound of poop suspended in "hair net", making for a very messy situation.
Damn Tyler, I know you called the bathroom right after I pooped, but it was a must that I shower immediately after running into a Sinister D. Hopefully I won't shower shart while I'm in there and prolong the process.
