Registered Nurse- "Can someone call an RN?"
Right Now- "I'm over here stroking my dick rn I got lotion on my dick and I'm just stroking that shit"
Real Nigga- "Tyrone over here acting like an RN"
Derived from RNG or Random Number Generator. Typically used in video games due to the luck of a random number generator being represented as a Miracle or Divine intervention and thus the character of RN Jesus is prayed to or thanked for Luck. Most situations where RN Jesus is invoked involve games with Random Criticals like Fire Emblem and Team Fortress 2.
"I have a 1% chance of getting a Critical Hit and RN Jesus blessed me." Then later... "Why RN Jesus, why? I had a 99% chance of hitting that!"
