Well That's Fantastic 

Used as an ironic reference to the fact that it abbreviates as WTF. Said whenever someone gives you useless information about their life that you don't know how to respond to

Random Acquaintance: I bought this cheeseboard from Waitrose and it doesn't even have Wensleydale!
You: Well That's Fantastic (read: I do not care one bit)
