Forum:"Cooking" grenades?

I recently saw this term in one of the wiki pages. I believe it was tied to a medal of some sort, but I digress; what does the term mean, and what is its use in combat?

Also, for the purpose of further discussion, what other well-known tactics or strange/silly tricks are there for Black Ops II that have odd names like that?[Cooking, 360 no scope, and dozens of others I've heard of but not investigated]

Perhaps if enough contributions come around, this could become a resource of sorts? In any case, I look forward to whatever you guys can tell me....
