look up any word, like bukkake:
 
1.
Ascending or descending the stairs with full intention of accomplishing something, and completely forgetting why you had gone up or down after returning to your initial floor.
I rush upstairs and stare in the bathroom mirror for like 2 mins and only after slowly going back down did i mean to brush my teeth- total stairnesia!
