This is a phrase we are using a lot these days. It is not particular to Morocco, but its use has increased ten-fold since we've been here. The exchange is usually as follows:
'You know what sounds good?'
'What?'
'That pumpkin pie that is mixed with whipped cream so it is really light and custardy and usually called something like Chiffon Pumpkin Pie.' (This is Ryan's)
'Oooh. That DOES sound good.'
The only real variation to this exchange is whatever sounds good to the person. It is almost required that you agree with the person's craving though. I don't know why, but it is just nice to respond with affirmation.
You know what sounds good?
Fish tacos made with some type of beer-battered white fish, crunchy cabbage and chunks of avocado on warm corn tortillas with plenty of hot sauce.
Also: The exact cheese enchiladas I had with Jane in San Diego on that little patio in Ocean Beach with crunchy lettuce and thick tortillas...plus parrots squawking in the trees...plus Jane.
