Someone who gets pat on the head for their political beliefs / Someone who has the same opinions as the people who surround them / Someone who takes the same opinions as their family/ Someone who has opinions that can be expressed with the same difficulty as putting on a slipper.
Example:
"Jessica don't be a Slipper "
"David your opinions are the same as your parents , your'e such a Slipper"
"Gary your opinions have brought you no difficulty in your life stop getting so worked up, your'e being such a Slipper"
An older slapper. Sometimes used to refer to the mother of a slapper. An older woman, usually tartily or trashily made-up and/or dressed, who gives the impression of, or has the reputation for, being free with her sexual favours.
(Reference: Probably refers to the footwear favoured by older people, particularly. Comment / interpretation: Perhaps she has hung up her highheels / white stilletoes and now goes for easy to wear, comfortable bedroom slippers? Thus, )
Kayleigh is a right slapper, but whatd'you expect with a mum who's a slipper?
