The 4JX1 is an incontinent diesel engine which is best known for mixing diesel, coolant and oil before the vehicle can even leave the dealership. It was installed in the Isuzu Trooper and GM/Daewoo/Holden Jackaroo and was the most reliable part installed on those vehicles. The engine was developed in partnership by Isuzu, a toddler with a broken crayon, and Caterpillar (the insect, not the construction equipment manufacturer). 4JX1 owners can usually be found at home trying to repair their junk, or at the side of the road waiting for a tow truck.
"Do you sell any parts for a Jackaroo with a 4JX1?"
"GTFO of my store!"

"No we can't make your 4JX1 reliable. No-one can"

"It's a 4JX1 thing. You wouldn't understand"

Although it is extremely painful for the victim, it tends to be considerably funny to people who witness it.

Serial Monogamist 

Someone who jumps from one relationship immediately into another one.

Serial monogamists can not stand to be alone and often suffer from vast commitment and insecurity issues.

Because they jump into relationships immediately after the previous one has ended, serial monogamists typically don't take the time to reflect on their behavior or why their previous relationships failed; thus, they end up making the same relationship mistakes over and over again.
Person 1: Damn, Dustin already has a new girlfriend?! It's only been two weeks since he broke up with his fiance! I think he's a sociopath.

Person 2: No, he's a serial monogamist...
