To end a phone call by slamming it violently on the ground. The motion resembles how an NFL player spikes the football on the ground after scoring a touchdown. This action usually destroys the phone completely which is why it is such a rare and exciting event. Most likely derived from the football slang term pick-house.
"I knew Steve was completely wasted when he took his phone-house in the middle of the bar."
"I was so pissed when I found out she slept with Jake, that I took my phone-house."
