Jeffing

The act of sending unintelligible, often misspelled, texts that are chock full of grammatical errors and acronyms that only have meaning to people named Jeff.

Stop Jeffing me, I have absolutely no idea what that text means.

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.

James J. Jeffries

A heavyweight boxer also known as the "boilermaker" who fought consistently from 1895 until 1904 beating such legends as Bob Fitzsimmons, Jim Corbett, Peter Jackson and Tom Sharkey and retired undefeated. He was like many at the time, a staunch racist, and when the legendary black champion Jack Johnson won the heavyweight title, he foolishly agreed to "put that N*gger in his place" despite the fact that at this point he was morbidly obese and retired over 6 years. After extensive training in fitness and sparring (and many more insults to Johnson), the bout was deemed the fight of the century, and the vast majority of white people bet on Jeffries despite the major fore-mentioned disadvantages. As expected, Jeffries lost in humiliating fashion while Johnson grinned and toyed with him for 15 rounds before knocking him out. Many white people were so butthurt they began killing random black people and even each other. Jeffries undefeated record was now destroyed, but he took the loss with humility and admitted he couldn't land a hit on Johnson and lost fair and square. He stayed retired afterwards, and remained a public figure until his death in 1953.

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!"
