The English word sinister comes from the Latin word "sinistre", meaning "left". So, since she's sexy and left-handed, she's a sinister sister.

A one downin' fool you might encounter at your friend's mamma's house. Usually found lookin for purple stuff in the fridge on his way down to the basement where he might try to play uriah heep bass lines and poke holes in your rubbers.
Dude, if you can't already tell from the easy livin' riff, sinister finister is downstairs. I think he broke your dad's treadmill and oh yeah, you might want to double wrap your pickle if stacey is comin' over later.

God of the bass. Known to hang out with Nasty Maggots. A Cabbage Night Orchestra staple. All tremble in his presence, not due to fear, but rather to the low-frequency rumbles from the 4-stringed instrument of Satin (not Satan, but Satin – dark overlord of the underworld of disturbing artwork). “Sinister Finister”…the uttering of his very name causes your car to stall, your guitar to detune or snare drum head to break. An evil, evil presence which must be stopped in our lifetime, before somebody pokes an eye out.
Man, I went to see the Nasty Maggots last night, and Sinister Finister was there, and after the show on the way home, we were talking about him, and my car stalled!

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 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.
