Right Handed Sinestro 

When having sex with somebody from behind, the receiving partner reaches back with their right arm and forcibly attempts to jam their fist up the ass of the giving partner. Named after Thaal Sinestro, the arch nemesis of the Green Lantern, the name is a reference to the fact Sinestro wears his power ring on his left hand so his right hand is free to penetrate people anally, as most supervillains often do with their free hands.

guy 1: I was having sex with this girl last night and I stuck it in her ass without telling her first.

guy 2: hahahaa what did she do?

guy 1: she wasn't happy so she gave me a right handed sinestro to get even.

guy 2: Oh man that sucks!

guy 1: ...I kind of liked it (._.)

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.

Sinistral 

An arrogant fascist with an inflated opinion of himself. Usually holds power over a chatroom or internet forum and seems to think that makes him a deity. Feels a constant need to demonstrate his supposed superiority by attempting to belittle and humiliate others. Doesn't really care about anyone but himself, and once someone stops worshipping him he will treat them like he does everyone else.

Goddamn Sinistral! Who the fuck does he think he is?!
