What is the most common way to use "overkill" in day-to-day life? Someone i know from America told me that they always use "overkill" like this way:That's enough ,anymore is overkill.let's say if you guys are at a restaurant and someone are trying to order more than can be eaten up. but when i looked it up at the dictionary i can't find such a usage anyway, so i 'm really wondering if it makes sense ? or its not that common? if you guys do use it this way, then can i have more examples here? thanks. ;p
