When you stick your finger up someone's ass so deep you reach there intestine track, then your finger proceeds to slide and do loop de loops in there intestines
Name for when a woman excretes too much lubrication from the vagina. Sometimes nice but sometimes a pain as it can result in a loss of any sensation for both parties during intercourse.
I was trying to have sex with this woman and it became a slip'n'slide.
I could not feel anything as a result of the slip'n'slide.
