Euphemisms are common in today's society. They're basically "sugaring" up something really negative to make it sound positive. For example, someone a mausoleum can be a "place where people are sleeping" or the mentally retarded being "special needs" or whatever...It's not really that advanced of a vocabulary word...I suppose.
That being said, it's ironic on how sometimes when euphemisms are used to replace a word with heavy negative connotation, society will eventually make that euphemism carry a big heavy one. That's really my only thing against it, but hey, that's just the general people. You can get really creative with these things, like figurative language, so that's a big plus~
