While railing a girl in the ass, right before you are about to bust, take out your dick, and shove your thumb up the browneye. After the thumb is inserted, spit on her back causing her to turn around. As she is turning around to look back, pull out your thumb and glide it across her forehead while reciting "SIMBAAAA" just like Rafiki from "The Lion King".
I was gonna go down for a quick tug, but my girlfriend preferred if i gave her a Sneaky Rafiki.
When a man is having sex he will look in the others poopsock. Stick his thumb in it, and as the person looks behind them with the first persons uses their thumb to rub a line on the second persons face and says “simba”
When a male ejaculates on a female's chest then takes 2 fingers and rubs them in the ejaculate, he then smears it across the woman's forehead while saying "Simba"
A sexual act involving the period blood of the ladyfriend you've been plowing being placed on her forehead using your thumb. It is directly followed by you gently calling her "Simba".
Guy 1: Dude I gave Jess a sneaky rafiki last night!
Guy 2: ...... That's fucked up man.. *gives huge high five*
1. A person who pops up on IM at the least expected moment; especially if they pop up right after they said "g2g" and logged off. This is similar to how Rafiki suddenly disappears and reappears at random moments in Disney's 'The Lion King'. Particularly in the scene where Simba is chasing Rafiki through the jungle, prior to Mufasa's appearance in the sky.
2. When you email someone a question, and as soon as you hit send, they pop up on IM and answer your question. This is called "a Cyber Rafiki", or "Pulling a Cyber Rafiki on someone". Just like how Rafiki knows the answers to all of Simba's questions about his father Mufasa.
1. "Bob is like a Cyber Rafiki. He always says he's g2g, logs off, and then he's back online two seconds later"
2. Jim: "I just emailed Heather with that question and she pulls a cyber Rafiki on me".
Larry: "What do you mean Jim?"
Jim: "As soon as I hit send, she answers me on IM. I didn't even know she was online. So, random".
