Is that really a verb?

Last night driving home from work, I got a call from my brother-in-law. We'll call him J.P. "What resturaunt are we going to tonight for your birthday?"
"I don't remember, why?"
"It isn't (censored) is it?"
"Actually that sounds right."
"Oh man! I was nailing this chick that works there." (nailing? really? is she a vampire?)
"So I take it you're no longer.. um.. 'on good terms."
"No"
"So I'll not be ordering what you are, just in case she spits in both of them to make sure."
"She wouldn't spit, it's her boyfriend who works in the kitchen, he sure would."
"Right, so I'm double super not ordering what ever you do."

Good times.
