This can be defined as anything that is "tight," "smashin," "hot," or "tastes good." The phrase is used in strong like, or excitement about something/someone/someplace.
A guy is walking by and you think he is hott, you lean over and whisper to your girls, "thats some jerk in a can!"

You are shopping and you see a pair of jeans that just rock.. you can't help but yell out "damn, those are Jerky in a can!"
