Sentence:  It transpired that Mrs Egg had been cooking dinner when she discovered Mr Singlet making himself a sandwich. I don't know about you but it does seem a little bit naught after she's gone to all that effort. Naughty yes but hardly a crime and certainly not enough to warrant a 999 call. Yet that's what she had done. That&#39;s why we had left our own dinner, charged through rush hour traffic, disrupted commuters on their way home – all for a <WSD>cheeky</WSD> sandwich. 
Meaning of the word marked with <WSD> tags:  Indulged in.
