look up any word, like daquan:
 
1.
Someone who won't let you talk about a TV show around the water cooler at work, because they have it recorded.
"Hey did you guys see the Office last night?"
"Shh! don't say anything...I have it on my DVR."
"What a cooler killer!"

an overweight person at an outdoor summer event who sits down on and damages the cooler
You see that big woman over there - she is a cooler killer, that cooler will break if she sits on it.
