Two things:

1: TIL that this hugely annoying thing that’s bugging me since childhood has a name.

2: that disclaimer before the article 😂

Screenshot Wikipedia article about Tendril perversion. A geometric phenomenon when a spiralled chord messes up in one place. 

Disclaimer before the article: This article is about the geometric phenomenon. For the pornographic genre, see tentacle erotica.
Article:
Tendril perversion is a geometric phenomenon sometimes observed in helical structures in which the direction of the helix transitions between left-handed and right-handed.
Such a reversal of chirality is commonly seen in helical plant tendrils and telephone handset cords.
