A dude with a really small dick. Small enough that it just barely penetrates the inside of a woman, causing the rest of his body to just grind the womans vaginal opening.
The guy I took home lastnight was a real vagina grinder I totally couldn't reach an orgasm.
A girl who is a bitch but hot. Usually one out of a group of friends drags the others to the Vagina Mcginesteen's house. The person who drags his friends along is just looking to score, NOTHING ELSE.
The friends being dragged along hate the Vagina McGinesteen, therefore they change her name to Vagina Mcginesteen.
Person 1: Dude can you believeSeth dragged our fat asses to Vagina Mcginesteen's house. She is such a btich.
Person 2: Ya but she is hot. I still hate her.
