But Wait... 

Used to abruptly end a conversation or statement when the user has nothing else to say as a comeback. Quickly gets old. Should not be over used. Should have something added to the end for extra effect.

Joey: Yeah your moms ugly as hell... I mean she's so old that...

Joe: But wait... Shutup!

But wait, there's more! 

The cliche phrase uttered during every infomercial that doubles and sometimes triples the amount of stuff you get if you buy the product. Because everyone needs 128 sticks of mighty putty!

Informercial: Call now for your new space saving vacuum bags. But wait, there's more! Call in the next 5 minutes and we will double your order. That is 2 sets of bags for the price of one! Call now.

Consumer: Wow! What a deal. I have to order those.

But wait, did Adolph hit her? 

A clever saying that rhymes with "Adolph Hitler".

"Have you ever met Adolph's wife?"

"No, but I've seen her pictures on Facebook, she had this fat bruise."

"But wait, did Adolph hit her?"
