Sinister Finister

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.

sinister strike

A noob attack in World of Warcraft that only noob subtlety rogues would use in order to waste more energy instead of using hemorrhage. However, it is a vital skill for combat and assassination rogues because it is about the only attack that they can spam in order to gain combo points. Some combat rogues also prefer sinister strike with improve sinister strike talent.

rogues typical chain combo
sap - cheap shot - Sinister strike - Sinister strike - kidney
Sub rogues
sap - ambush - hemo - hemo - kidney
(or something like that)

Sinister Finister

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!

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.
