Mutton dressed up as lamb is when a slutty older woman thinks she can tart herself up and look like a younger innocent girl. See Gretel Killeen from Australian Big Brother.

A dirty older slut that wears barely anything and then tries to make out she's virginal.

When a guy or girl injects so much Botox in their face that they think they've just turned sweet 16 again, when in fact they're just the same cheap drunk they were before!

1. To wear younger skimpy clothing.
2. To wear so much make-up that you could pass as Michael Jackson.
3. To not act your age.
4. To be a total slut and think nobody knows how many guys you fucked.
5. To expect that all the housemates on Big Brother will bang you before and after the show.
