Define Uncomfortable Silence Meaning

Uncomfortable Silence
If you hate when people say "awkward silence" you can tell them to shut the fuck up about it and wait for the uncomfortable silence that comes after.

from Pulp Fiction

Mia: Don't you hate that?
Vincent: What?
Mia: Uncomfortable silences. Why do we feel it's necessary to yak about bullshit in order to be comfortable?
Vincent: I don't know. That's a good question.
Mia: That's when you know you've found somebody special. When you can just shut the fuck up for a minute and comfortably enjoy the silence.
