Happy butt 

When things are going well for you.
An extra little bounce in your step.
A really good mood.

Sally: "You're in a good mood today!"
Dave: "I woke up with a good dose of happy butt!"

Butt Happy 

When you're incredibly happy about something.
So happy in fact, that your enthusiasm could easily be perceived by others as you being gay for said object of affection.

Butt happy is the antithesis of being butt hurt.

Mikey was all butt happy when he heard that Tool was playing a show in downtown Austin.
