When you wank so hard or so much you exhaust yourself and immediately need a nap to recover.
Clean up of busted nut with a gak towel is highly recommended prior to the stroke nap. Otherwise, one wakes with their cock glued to their leg or abdomen and fingers and pubes may be adhered with an opaque crust.
After watching porn and wanking for two hours straight, I needed a stroke nap.
I wanked and nutted so hard I passed out into a stroke nap. Unfortunately, I woke up and my thumb and index finger were glued together with my cock snot.
When you wake up from a nap even more tired than you were before you took the nap....and youre hungry as shit.
"Ive got nap stroke....get me some fuckin chicken."
