The practise of gobbing, flobbing, or grollying, on to the inside of the roof of the bikesheds, to see who could get the longest "hanger". The length of time it remained suspended meant extra kudos. A kid called Terry Nugent was the undisputed champion, because his invariably contained blood. Which is probably why you don't see Player's No. 10 much anymore...

With the correct consistency of phlegm, hangers could remain hanging from the ceiling for weeks, even months. It's a volume to consitency ratio. Particularly good on textured ceilings.
