Is "Are you yelling here?" no good?
It should be. :)
I would rather translate that as sikítotok, sikoltotok, or in some cases as ordibáltok or ordítotok.
ah, this spot is already taken, then I will just go shout over there
So this is plural? I still struggle recognizing them.
Yup. The suffix -tok, -tek, -tök is for 2nd person plural conjugation.
