I feel like this should be more widely known, but for some reason is just hasn't caught on and most people still have no idea what it is. From my own experiences of bringing it up with friends and co workers, it's been a mixed bag of "I do that too!" to "Whatever, lets go get drunk". I feel like most people just don't care enough or understand how awesome it is and are too lazy to put forth the effort it takes to actually learn how to have them. It's very easy not to, of course, as I forgot about it myself for over a year...
