Recalcitrant: stubbornly defiant of authority, disobedient.
( Ree-Cal-Sih-Trant )
The recalcitrant teens continued their graffiti assault on the wall.

Sishum: special, of importance.

Oyami su sishum ijan.
They are very special.

[ Because "su" was used, the word "special" is used as an insult, meaning they are slow. ]
