Crummy Buttons is a term for disappointment in any given situation. I first heard of Crummy Buttons on the Andy Griffith Show.

Internet persona(s) who happens to follow you and you happen to follow them back and maintain communication with and have a mutual liking for eachother whether it be friendship wise, etc. (Mutuals if more than one mutual)

Originally, a sponsor of the fictional Alan Brady Show which formed the plot lines the 1960s hit, The Dick van Dyke Show. On DvD, no one liked Crummy Buttons candy even when it was offered or free. It has, in some circles, come to represent any unpleasant surprise or disappointment.
