Bidding, in the context of sorority recruitment, refers to the process of offering a formal invitation, known as a bid, to a potential new member to join the sorority. If a PNM receives a bid, she is invited to become a member of the sorority and has the option to accept or decline the invitation. The bidding process marks a significant milestone in sorority recruitment and opens the door for the PNM to become a part of the sisterhood.
