boocoo dinky dau or beaucoup dien cai dau 

Crazy or crazy in the head. Derived from half French half Vietnamese. Boocoo (Beaucoup) Dien cai dau (Crazy, or literally "crazy head").

A phrase used by Vietnamese street vendors to American GI's to suggest that GI's bargaining offer is crazy. Before Americans stepped onto Vietnamese soil the French were there for around 150 years so their influence can be seen.
1) GI: I will give you 10 cents for that pack of 555 Cigarettes.

Street vendor: "boocoo dinky dau or beaucoup dien cai dau", see-ga-ret phip-tin xu (cigarettes, fifteen cents/piasters).

2) Michael J. Fox: I told them, and they don't care!

Sean Penn: You dinky dau, man, you're "boocoo dinky dau or beaucoup dien cai dau"!! (You're crazy man, you're very crazy in the head!!)

No reference to chicken as suggested by some online interpretation. Although the Sino-Vietnamese word for the Chinese zodiac rooster is Dau there are two kinds of Ds in the Vietnamese language 1) a hard D as in the word Dick, Don, dog; and a soft D prounounce as a Y in the beginning of a word as in Young, yearn, year. The zodiac rooster is with the soft D as in "Yau" not the same as the hard D as in Dau, head.

3) HBO SHOW True Blood: PTSD suffering Vietnam Vet Terry wears a T-Shirt with "Warning: : Beaucoup Dien Cai Dau: I suffer from occasional loss of mental stability and become very violent with only slight provocation. The Veterans Administration has determined that both mental and physical harassment of my person may be hazardous to your health and well being. So stay the hell out of my face. Thank you"

It is said of the situation where a person has the bad luck to make contact with his testicles against an undefined surface or object, intentioned or not.
Given the nature of the word, it is more appropriate to design cases where the interaction is made with a moving object, for example, a ball.
Although it is extremely painful for the victim, it tends to be considerably funny to people who witness it.
Today in the baseball game the pitcher took a nutshot; the baseball hit him in the nuts.

Man, I just watched the funniest nutshot video ever.

Nerd neck 

A "human" that spends so much time playing video games that their posture is level nerd neck. Everytime anyone goes tryhard they hunch down and their neck gets longer there fore a nerd neck is always hunched down cause they're always going try hard. In other words a nerd neck is a try hard, since their neck is 100% longer than the average human being due to playing too many video games and taking them serious, nerd necks are not even considered human anymore but something more sad. Nerd necks are often found on fortnite, their natural habitat usually being tilted towers.
What a fucking nerd neck!

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...
