Just as a 'cougar' is a mature woman with an affinity for younger men, a 'grizzly' is any mature black male but especially one with an affinity for younger women.
A subgroup of the grizzlies are the sen-taurs or senior black bulls.
Sentaurs are mature black bulls who specialize in pleasing younger White women.
A sentaur knows his place and is a vital part of a privileged White girl's well-being.
