Disappointed boing boing wasn't a West Bromwich Albion online fanzine although you will find the excellent boing by following this link. Only of interest to the elite few I guess.
Boing boing baggies baggies is the chant of the faithful followers of West Brom on achieving success (like a goal for instance). It all started back in 1991 when, in a game against Hull City (won 1-0, Darryl Burgess header second half) there was a sponsored bounce. Someone had offered a huge sum for charity if the whole crowd bounced for a minute. The chant began about half way through, perhaps influenced by a Eurodisco trend at the time.
During the 12 match run of defeats a few seasons later we ended up chanting:
We'll boing again
Don't know where don't know when
But I know we'll boing again some sunny day
Some sunny day
Favourite taunt (bit cliched now)
Boing when you're winning
You only boing when you're winning
