When two people of opposite or like gender agree to spend quality time together at late hours of the night taking part in physical and emotional activity.
A night sesh is when a boy picks up a girl in a trashy white car and brings her to a dollar theater movie to hold her hands and cuddle leading to an abundance of late night action! ;)
The act of uncontrollable sneezing, extremely watery eyes, sinus attacks, only happening after dinner when ketchup, or other vinegar products have been consumed or if ketchup packets have been in the vicinity of a Durgan.
At dinner I'll use ketchup on my fries even though it'll bring on a severe csse of night aydes.
I've been blowing my nose all night these night aydes are driving me crazy!
