\||/ L 

" Fo' lyfe", "For Lyfe", "Fuh Lyfe" or "Fah Lyfe". Replicates the four fingers on your right hand and the L shape on your left hand which you throw up every time you see someone.

Also, you can use it as a non-sequitur and show the sign as you stare deeply into somebody else's soul. They will not know what happened to them and over the course of the next three to six days, they will drive themselves to insanity due to the confusion which ensues from the seeing of the "For Lyfe" symbol.

Hey, insert anything here..." \||/ L "

A reference to an issue of a webcomic called Ctrl+Alt+Del, written by Tim Buckley. In this issue, called "Loss", the main character, Ethan, walks through hospital doors, talks to a receptionist, talks to a doctor, and sees his girlfriend lying on a hospital bed after having a miscarriage. Each of the lines are supposed to represent a character. This meme has lasted since its start in 2008, and is still relevant. It is usually accompanied by the phrase "Is this loss?"
