The following is in the lyric, "littlest things" by Lily Allen.

What I want to ask is the meaning of the word, 'dirt.'

Can you tell me?

• We`d spend the whole weekend lying in our own dirt.
It very much depends on the context....it could be a metaphor or a symbol.

I got the answer. Thanks^^.

A : This means "human dirt" ie: sweat, food waste, perhaps even excrement.

B: In this context not literally food waste or excrement though! The image in the song is of them in bed all weekend making love and not showering or washing, hence they share bodily fluids.

C : Yes, it just means that they haven't gotten out of bed, so they haven't showered.... In this context.
