Boy-speak Versus Girl-speak "We're gonna have fun"

Attention guys:

When you have plans with a woman, please tell her what you’re going to do.

Don't simply say “we’ll have fun”.

We hear: 

"I'm going to have a gown delivered to your house, drape you in diamonds and take you to the opera."

You mean:

"I’m gonna slap on some assless chaps, pick up a pizza and drop by your house."
