Jeep 4.0

An 4 cubic liter inline six engine produced by Jeep from 1986-2006. Used in XJ Cherokees, YJ and TJ Wranglers and ZJ and WJ Grand Cherokees. Well known for being one of the toughest and most dependable engines ever produced, it's not uncommon to see these motors running past 300,000 miles.

"You really have to try hard to kill a Jeep 4.0 , I drove my XJ into a pond and it stalled out. After I got it out and changed the oil, it ran fine like nothing even happened!"

AOL 4.0

Some jive ass internet from the 90's, back when clowns were rockin 2 phone lines to use the world wide web instead stealing that shiz from their dumbass neighbor that can't seem to figure out how to put a password on their shit. Unfortunately, some zip lock bags still use this shit for on-line gaming and ruin your entire experience, forcing you to call them out on their weak ass game and excuse for an internet.

Guy 1: I was balling out on some fifa until this guys connection went all AOL 4.0 on me
Guy 2: Shiiiiit, did LosDicenme24 strike again?
Guy 1: Yeah what a briar.
Guy 2: Man if I wasn't holding down Jacky's fine wine and spirits, I would have taken that jive ass zip lock bag down at least 2-3 pegs.
