Someone who's had a bad
day, and uses their negative
emotions against you, or someone in a terrible
mood who tries to make everyone feel the same way. All in all, they bring everyone down with their negative energy to bring themselves up. Similar to a party pooper.
Mary D. and
Elizabeth got so drunk at the
party last night, they woke up in a pile of vomit next to an old man. When they went to school, they dumped on everyone they saw. Everyone did not enjoy shit on their faces, so they called Mary D. and
Elizabeth "the day killers."
