P. Shitty
an adjective used to describe something that really sucks or has really bad quality, etc. 

 This word was originally just an insult for the faggot rapper "P. Diddy", but it eventually made its way to describing things.
1.)I would take you there myself, but my car is p. shitty. 
2.) Man, your guitar is p. shitty!
3.) This is one p. shitty piece of pie!
