Adjective for something that definitely wasn't lame, but not quite "hot". In other words, slightly below being hot, therefore warm, like a nice pair of mittens.

1. The biggest upset in football history (used by patriots fans)

2. The greatest thing to happen to the planet since boobs. (used by everyone else)
