It's a shout that dudes from (SLL) Finnish student organization uses to make everybody hate em instantly but it's still kinda funny thiNg. Actual meaning of this is - "Same group/local organization" . Used on big or small meeting's.
Very simple to use, for example if one person says -"I like gambina maidolla" and another one says -"I like gambina maidolla"
(Ps. Gambina is alcohol drink)
Then there must be silent brake about for a second after that both must scream -"SAMA DRINK"
J1- Hey, my name is JerrY and im from KAP(district of finland)
J2- Yo, my name is Jerry too and im from KAP...
-typical finnish silence
J1 and J2 : SAMA PIIRI(name in finnish)
