Closely related to the shocker. Insertion of the pointer and middle fingers in the vagina and insertion of the ring and pinky fingers in the anus.
I was giving her the shocker but she wanted more, so I stuck my ring finger in her butt and gave her the vulcan.

Get the Vulcan mug.
A race of kids of the underground music scene who adopted the hair-do closely resembling Spock from Star Trek whom was of the Vulcan race. Most known for this hair style and culture were the strange faggish members of The Locust and it's followers back in the late 90's. The Hair style evolved into a more uglier look unfortunately into the Emo scene- which also unfortunately surfaced due to lost teens who unknowingly acquired the style in the last few years, they added some length, modernized it to fit mainstream style but did not achieve to keep it non-queer, gay looking or faggish. It's not believed to be known to them that it does look gay as hell. In fact, Mullets should of came back out of the trailer park before a faggot hairdo like this.
"Oh great, are band is opening for The Locust? Fucking dumb Vulcans."
"Look! The place is full of Vulcans."
"There's a Vulcan sucking wank for the joy it, and they are both male."
