swah-hee-lee-an bak-slap When receiving oral while standing, right before ejaculating, the person receiving oral defecates on their hand, and proceeds to slap it on the back of the person who is giving the oral.
Lilly: "So like omg, i was giving head to Billy and right before he came he took a shit in his hand and slapped it on my back!"
Leah: "LMAO he so gave you a swahilian backslap!"
The act of using one of your fingers, swabbing the inside of your belly button, then giving someone a fishhook with the same finger. Tasty treat.
Rob: "Dude play with your belly button then smell it."
Vance: "Dude thats brutal.. watch this.."
*Vance gives Shane a Swahilian mouthpiece*
Shane: "Dude.. that tastes like Chinese food... :("
Sahiling, the art of sahiling which involves falling head first off of heights up to 5 feet. Ex: couches stairs mattresses to recieve the most damage to the brain as possible. The result of sahiling is loss of reason and the ability to form a proper sentance. Started by a local baby in abbotsford, sahiling is the scourge of the 21st century and must be stopped. Word on the street is other babies and even some adults have started to "sahil" to have fun and get high. If this isnt stopped, we will live in a genration with mildly retarded children who all want the thrill of falling off a couch headfirst onto the ground.
