do me a lemon

Means literally 'do me a favour'. The lemon part is Cockney rhyming slang, and is short for 'lemon flavour', so in other words it's really "do me a lemon flavour"

The usage is mostly to reject an offer or behaviour of some kind, due to its being undesirable in some way (as opposed to actually asking for a specific favour).

"Do you want to buy my iPod for 100 quid?"
"Do me a lemon. I could get one on ebay for 50."

Fucked a Lemon

A progression on the common phrase 'sucking a lemon' meaning to visually express irritation or disdain. To appear as though one has 'fucked a lemon' exaggerates this negative perception even further.

'Aditi's not happy, she's got a face like she's fucked a lemon'

Sucking a lemon

The look of disgust in a person that is reminiscent of the face pulled when eating something very tart, such as a lemon.

When my wife discovered that the paedophoilia charges that she had laid against me would not be pursued as the prosecutor had found them to be baseless she had a face like she was sucking a lemon.
