best insult 

Straighten up your own act before whining about the world, or if thats too much wear a blindfold, zip your mouth, and live in a cave.

This is an example including the word best insult.

best day ever 

Phrase you can blurt out when something good happens to you. In meaning combines "thank you," "how nice of you," "I really appreciate it," and "awesome" all into one expression. Meant to make the other party feel that something they did was well received.

Scene: Aaron is sitting on the couch watching TV and Wendy brings him the remote and a bowl of ice cream.

Aaron blurts out: "best day ever!"
