A sexual act which consists of one vomiting on a male partner's scrotum. The etymology of the name comes from where the act originated, which was at a Ruby Tuesday's restaurant in Texas, occurring whilst the song Ruby Tuesday was playing. The infamous incident happened when an unnamed Senator went to the bathroom to drop a deuce and was greeted by a drunken homosexual representative who was attempting to engage in fellatio. Due to the intoxication, all the representative could do was vomit on the senator's balls, before passing out, head in the toilet.
While at its core the act is considered accidental when attempting fellatio, there are certain subcultures which have embraced and adopted the Ruby Tuesday as a traditional greeting.
"My wife was going to give me head yesterday, but the previous night of partying resulted in a Ruby Tuesday."
