Murmur pants

[Lanell]

When a woman has a pair of [shorts], [trousers] etc on that are so tight that the [lips] of her vagina are showing. The meaning is derived from being able to see some lips moving but not hearing a sound.

[Merna]

A reference to the tight [leggings] which reveal the lips of the vagina. Often worn in the high street. English [Preston] slang derived from [murmur]. I can see the lips moving but cant tell what the cunts saying.
