Diffy in the jiffy 

Used commonly as slang in the modern videogame League of Legends, popularized by a Twitch streamer Tarzaned and many others, when one of the players in one of 4 lanes (Botlane, Midlane, Toplane, and Jungle) hardly underperforms in the Jungle role or gets outplayed by the enemy player several times, causing the game to be lost before 20-minute margin.

hitting the jiff jar 

When you engage in anal sex and when you're done you pull out and find fecal matter on your penis.(Jiff as in the peanut butter.)

"Last night I was hitting the jiff jar on my girl."

Jeffy in the Road

A minor inconvenience; a speedbump in the way of getting with a girl; the guy, who has an outstanding relationship with a girl, who you must bump out of the way to get with her

Guy 1: Man, I'd love to get with Jolanta.
Guy 2: I heard she has a boyfriend.
Guy 1: Nevermind him. He's just a Jeffy in the Road. He'll be out of the picture in a week.
