Over-enthusiasm

To give four cheers.

Three thumbs up!

To have a smile bigger than your face.

Being over the blue moon.

To give a hearty sphere of applause.

A1OK!

Cheering louder than yourself.

Not just showing up, showing off.

Applauding longer than yourself.

To raise the roof through the glass ceiling.

To bring the house down before setting it on fire.

To be the scream of the crop.
