obfun
Obfun is short for "obligatory fun." It refers to the ice-breaking activities that are injected into all-day seminars oe conferences either to make it more interesting to the participants, to remove any sense of dignity that might remain, and to lend variety to the activities.
The all-day conference consisted of six hours of lectures, and three occasions of obfun in which we lowered Hula-Hoops over each other, wore silly masks, and pretended that we were a herd of lemmings migrating for survival.
