A dirty trick where you lure someone in with one thing and then hit them with another. Like when you promise a pizza and give them a soggy biscuit.

'I said you'd get a pizza, not a soggy biscuit!'

'You said I'd get a date, not a guy who smells like a gym sock.'

'You said I'd get a job, not a job that pays in tacos.'
