Jeffin'

When your gut begins to throw a temper tantrum. Starting with biohazardous farts and slowly building to a terroristic level shit.

Dawg, I was in the middle of class when I started Jeffin'. It was brutal. 6 people died. I'm probably going to jail.

Jeffny

A pretty caring person with a loving heart. She is completely gorgeous, and all the girls envy her. She has a sexy body, a lot of guys like her. Popular, but has only a few close friends.

The new girl is such a Jeffny. She is so pretty and nice, and all the guys love her.

Jeffing

The act of reiterating exactly the same thing your friend literally just said, causing a cloud of annoyance and awkwardness amongst the group.

Colin: "Guys, I just ordered 5000 condoms online."
Wyatt: "Oh, I was just about to say, I ordered 5000 condoms online too!"
-_-
Colin: "Wyatt, quit Jeffing me."
Dylan: "Yeah, you're such a Jeff!"

Jeffing

1. The act of secretly jerking off on video chat in the bathroom while your wife is in the other room.

2. Using childish insults like fat, ugly, and poor when you don't know how to use logic to defend your point of view.

1. Girl 1: Who is that guy?

Girl 2: Just some loser who is always jeffing me on snapchat.

2. You know you've already lost the argument when you start Jeffing.
