what does "blin,nu priz kak govorit moya mama,pirojok na polochke))" means?

First of all, the phrase is written in Russian and this is forum for studding the Ukrainian language :) However, the Ukrainians are usually bilingual as the Irish (well, at least some of them), so they may know the answer.

In original in should look like this:

Блин, ну приз как говорит моя мама, "пирожок на полочке".

and perhaps it means: Damn. Well, the prize is, like says my mum "a pasty* on the shelf".

I'm not that good in Russian, so I don't know what does the idiom "pasty on the shelf" mean. :(

Блин (blin) means something like “(Oh) damn”, “(Oh) shit”. It's used usually when a person has not good reaction or mood in some situation and shows by word блин that he/she doesn't like it or something's wrong.

Ну приз (nu priz) means - “I mean the prize”

Как говорит моя мама (kak govorit moya mama) means - as/like says my mom/mum

Пирожок на полочке (pirojok na polochke) means - patty's on the shelf. It says that your mom allows you to take the patty(as a prize) because you've done something good.
