  Given a group acting on a Gromov hyperbolic space, Bestvina and Fujiwara
introduced the WPD property --- weak proper discontinuity --- for studying the
2nd bounded cohomology of the group. We carry out a more general study of
second bounded cohomology using a 'really' weak property discontinuity property
known as WWPD that was introduced by Bestvina, Bromberg, and Fujiwara.
