So you amp it up to 10 out of 10 and then your penis slips out of her vagina and stabs her in the butt hole creating a big bloody mess, causing you to stop having sex with her before you throw up.
Last night I brought this chick home and i totally gave her the rogo butterknife and now I have to wash my sheets.
