when in engaged in a sex act,(blowjob or intercourse usually doggy), the woman who has her hair braided or in dual ponytails, thus letting the man pull on them, these are called bitch handles. The lone pony tail would be a bitch handle. By pulling on her bitch handles the man brings his woman, the bitch closer to the action and let's her know who is boss.
Diane was giving me an incredible blowjob when I grabbed her bitch handles and brought her head to a firm position to jam it down her throat. Diane was on all fours taking it doggy style when I pulled hard on her bitch handles to ride her harder and make her grunt.
