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.

-See shower shart

synista

The way a dumb emo with a bad haircut spells sinister.

He needed to save ink to put around his eyes cause his mum confiscated his mascara, so he spelt sinister with two less letters. WTF is a synista?

sinister slice

1.) When a man repeatedly returns to his ex-girlfriend/ex wife, even though he hates her, just for the sex.

2.) being pussy-whipped to a girl your friends and family hate. often friends will try to separate the victim from his assailant.

"Dude, where's Jack? He said he was gonna meet us at the bar?"
"He went back to Jill's again,"
"Looks like he's got a case of the sinister slice again. we gotta get him away from her, for good."

Sinastare

To maintain eye contact and friendly banter with an acquaintance whilst mentally performing outrages sexual acts.

While the conversation was friendly enough, when she mentioned her daughter’s netball team, he returned a smile and a Sinastare that sent a shiver down her spine. “I think I’m going to go,” she said. Zed smiled again and said nothing.
