neat bones

very cool, either literally
or sarcastically.
(a cross between "cool beans" and "neato".
the result of thinking faster than you can talk while describing something cool, or while mocking something.)

1. you: OMG! i love you!
me: NEAT BONES!

2. you: i ust got the new harry potter book!
me: *looks at you for a while* neat bones *smile*
