A term used mostly by ice climbers to describe the feeling of having your hands go numb only to come back to feeling with extreme pain. The terminology coming from when your hands are coming back to feeling you want to scream and barf at the same time.
I was climbing that sick WI5 but when I got to the top I had a nastycase of the screaming barfies.
The disgusting domino effect caused by one person vomiting on another, thus continuing a vomit cycle. Typical hot spots for barforama include classrooms, roller-coasters, airplanes, and viewings of the Saw movies.
"When the roller-coaster turned upside-down, the guy in the front barfed and it splattered the other passengers...the rest of the ride was one massive barforama!"
