When something goes right for someone, specifically the boys
Person 1: "I just had a threesome!"
Person 2: "YEEYAH SMIRNS"
An exclamation to invoke a sudden urge of attention and immediate warning. Used by elders and parents of the diné tribe to intervene upon an urgent alert where verbal warning is needed. Also "yeeyah" would be introduced to a situation where one may be correcting or guiding a child away from an immediate danger such as a poisonous plant,animal,etc. However the severity of the word fades as one assumes the age of adulthood where things of "yeeyah" in nature takes on newer forms.

Parent male: yeeyah! Don't touch that! *reference stovepipe*
