Selactose intolerance 

A person who isn't lactose intolerant but says they are to all dairy products..... except ice cream

Selective lactose intolerance

Patient: um yeah they messed my dinner order up again. It has cheese on it and I can't have cheese

PSA: I apologize. Are you lactose intolerant?

Patient: yeah

PSA: Again I apologize for this. I will get all the dairy off your tray and place a restriction so no more will be brought in. (Picks up CHEESE omelette, 2 pints of chocolate milk and ice cream while patient watches sadly thinking he isn't getting anymore ice cream now)

Patient: (sarcastically) umm thanks

PSA to another PSA
PSA 1: so apparently he isn't lactose intolerant he has selactose intolerance
