Taking
something that someone finds joy in and describing it as joyless and inferior. Taken from lake
swimming where you can find occasional warm spots; telling someone about it
may lead them to come over to share the warm spot, only to take a piss.
"I am in
love with this video. 1000 musicians got together to play a song to get foo fighters to come to their tiny
Italian village."
"I guess. I prefer the actual Foo Fighters version though if I'm going to listen to
something."
"Stop pissing in my warm spot."
First person "Pissing in one's warm spot."
