Not to be confused with Persian, A Peishan is a very beautiful asian girl who is smart and funny; and who will always make you laugh. She is not afraid to ask for help, and can sometimes be a bit stubborn. She is also somewhat promiscuous and flirty, but it is all her qualities that make her a gorgeous and successful person.
Any guy would be lucky to have her as a girlfriend
Dude *looking at pic*: So, what's your girlfriend's name?
1.) nerdy or dorky. 2.) "hugely winning" (as in, "what a fucking winner"). 3.) a term used whenever the impulse to laugh is created (i.e. embarrassingsituations).
An entity of absolute truth. One of the fundamental laws of physics is that 'Peishi is always right.' Failing to maintain this law means that one is 'damn cui'.
