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.

a word used to convey that it has been awhile since something last happened.
This word was originated at Stiver's Bar in Chelsea, Mi.

'Hey man, I haven't seen you since, uh, fuckin, uh, (sinsafuckinuh) last Tuesday!'

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

Sinsanity

When people try to make it look sane that they change the Bible words and basic moral code just to fit their need in life to make them look like they have sanity in their point.

Every time I talk to her it is sinsanity because morals don't change to suit her needs.

Sinsatshun

The feeling you receive from sadistic masochistic sexual relations.

The sinsatshun I felt from S&M play was out of this world!
