I ask, forgetful of the familiar sense of bestie, and figuring cougars at least by the word.
Chances are that you know at least one person -- mother, sister, wife, girlfriend, "bestie," maybe even yourself -- who has popped the little pill at some point in her life.
She wants to be everyone's bestie.
Common backgrounds don't necessarily mean you are introducing me to my future bestie.
After all, who among us hasn't at one point suspected that our former bestie was secretly the devil?
