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"
