Interior Decorating 

To slap a bit of white around the womb using the naughty paintbrush.

Friend 1 "Hey Picasso, did ya do any interior decorating last night?"
Friend 2 "Yeah, with your mom, zing."

Interior decorating 

After eating 50 buffalo wings and a McFlurry, you bend over in front of the wall and paint the walls with your spraying shit.

Dude, I just ate so much shit. I really think my bathroom needs some interior decorating. I'll be right back.

When we got back from wings to go, my friend paid me to interior decorate my bathroom. He did a pretty pleasant job; it had a full smell with a nutty note to it.
