Pissin is when you have something that is fake like shoes or a bag and someone compliments you on it and you flex that its fake by saying you're
pissin. You can also call someone out for pissin. If you steal someones item not knowing it was fake and then find out or if someone sells you product they claim is real and ends up being fake, you officially got
pissed on. You can also say that you don't need to piss because you have the money to buy
the real deal.
