A Party-Reaper is someone that joins a playstation,xbox party, or voice call that nobody likes and often says snide remarks that "kill" the voice activity or cause everyone in the chat to go silent out of awkwardness or just pure hatred.

It could be said that the Party-Reaper is there to claim the soul/life if the party.
"What a f**king Party-Reaper, just had to be a prick"
"Ah speaking of the Party-Reaper, "(everyone would then go quiet due to awkwardness or hatred)
