Word for someone who when leaving a room makes it feel like someone has entered

I'm looking for a word that describes the following:-

"When they left the room, it was as if someone else entered".

I vaguely recall reading a Yiddish term that described this in a novel many years ago, but all I can find is Nephesh - soul.


Solution 1:

The Yiddish word you're referring to is Nebbish:

a timid, meek, or ineffectual person - Merriam-Webster.com

Possible alternatives: Complete Non-entity, Oxygen-thief.
