This sounds like Balderdash. http://www.amazon.com/Mattel-B9176-Balderdash-Game/dp/B00009...
That said, I expect it's pretty fun to play - Balderdash is the only game we constantly come back to, every Christmas, without fail.
Good luck to them!
I'm thinking that this is to Balderdash as Cards Against Humanity is to Apples To Apples. (At least from my understanding. I haven't played Cards Against Humanity.)
