look up any word, like spook:
This is when you have dirty anal sex with some slut and then shove your nasty fallice in her mouth...the result is similar to when you ate shocktarts as a kid and your cheeks pucker in as well as her mouth.
yo I pulled a shocktart on this chick, you should have seen her when she was done she looked like Renee Zellweger

A little used term for one who is fond of Feeling Electric, now known as Next to Normal.
Girl 1: That fangirl constantly quotes Feeling Electric, she's such a shocktart!

Girl 2: What's Feeling Electric?

Girl 1: It's like Next to Normal, only more epic.
