premedicated murder 

When someone kills and then uses an insanity defence.

Mayuko: Did you hear about the Tampa mom who shot her teenage kids for being mouthy?
Phil: What the?
Mayuko: Yeah she said that she snapped but it turns out she had it all planned.
Phil: Good luck using the premedicated murder defence.

Noriko: That Greyhound bus beheading guy was totally crazy don't you think?
Paul: Yeah, premedicated murder for sure.

premeditated self-defense 

Planning to enter a potentially violent and/or dangerous situation with a lethal weapon in order to feed a fantasy of justified homicide.

Yeah, Kyle went down to that protest with his AR to "protect" the business, but really it's just premeditated self-defense.

premercial 

Right before a TV show goes to commercial,
1a. the short "teaser" that attempts to entice you to continue to watch the show, or b. recaps what went on during that portion of the show
2. Needless filler for shows lacking content (see also: postmercial)

What's the point of watching Survivor anymore? The premercial already showed us who will win!

The premercial shows two contestants getting into a catfight! I can't wait for the next segment!

Why does Iron Chef America always have a 5-minute premercial recapping what just happened? Do they think we already forgot what happened 10 minutes ago?

Dude 2: Dude that was me!
