When you fuck a house up so bad from a party it causes future parents to say no to their kids when asked about having a party
“Hey did you hear about the huge fucking party mike had?”
“Nah what happened?”
“Like 150 people showed up and were phelpsing the fuck out of his house”
“Wow! Holy fucking dick cheese!”

When I go phelpsing, I make sure I have nothing important to do afterwards, because I'd be too high!
