English in a Minute: Over the Top

Welcome to English in a Minute! 
This is the bottom and this is the top.
But what does it mean to be “over the top”? 

Anna: Dan, one of Caty’s pens is missing! 
Dan: She probably lost it. Besides it’s just a pen. 
Anna: No, no, no. It’s her favorite pen.
First, we interview witnesses.
And then, we dust for fingerprints!  
Dan: Don’t you think that’s a bit over the top? 
Anna: Dan, this is the case we’ve been waiting for!
Dan: We? 

“Over the top” is used to describe something that’s too extreme or requires too much effort for a situation. Some decorations or clothes are over the top. So is collecting fingerprints to find a pen that I borrowed!
