Here's a sentence from a patient speaking to her youth psychiatrist:

> 
> Weil Sie auf das, was ich sagte, keine Emotion zeigten, nur eine Antwort ausspuckten: Blob. *(Source: [DIE ZEIT ONLINE, 1 December 2016](http://www.zeit.de/2016/48/jugendpsychologie-suizid-therapie-beziehung))*
>

What is the meaning of the term "blob" here (and are there any other meanings), and what is its etymology please? Is it correct to assume that this is a rather informal term?
