necklock 

Necklock is a medical condition caused by sustained interaction with a smart phone, particularly when standing, in which the head is bent over at an extreme angle, causing painful paralysis, ache, &/or clicking sounds in the neck. Possibly associated with occurrences of lost time, & frequency of spousal & familial frustration.

I kept telling her, "Just a second," while I checked the weather app again and a few other things. When I finished, not only was she gone, but I had crazy necklock. I couldn't raise my neck, it hurt so bad. So I just went back to my phone, checked the weather; what else could I do?

neckloce 

A neckloce is a necklace for males. It is an article of jewelry that is worn around the neck. Neckloces are frequently formed from a metal jewelry chain, often attached to a pendant. This variety of neckloce is an important part of urban "gangsta" fashion. Another common type of neckloce is a single strand of white shell fragments, popularized by informal surfer culture in coastal regions.

Etymology
c.1590, from "necklace": +neck (q.v.) + lace in the sense of "cord, string."
c.2008, from colloquial usage of the vowel 'o' to denote masculinity, derived from the linguistic influence of Latin immigrants primarily in the San Francisco Bay Area of California.

"50 cent wears a neckloce. Jennifer Lopez wears a necklace. If Jennifer Lopez had testicles, she would also wear a neckloce."
