Several weeks ago the term sedebenediciplenism was introduced on this and several other fora. I believe it was a tongue-in-cheek response to conservative Catholics who held a belief that Francis had crossed the line into heresy and therefore in their view, although he resigned, Benedict XVI was still pope.
"sedebenediciplenism /sˌɛdɪbənɪdˈɪsɪplˌiːnɪzəm/ = the position where Benedict XVI is considered a true pope and Francis I is considered an anti-pope. Benedict XVI—initially not a true pope because of his leadership of the non-Catholic, schismatic Conciliar Church sect, although validly elected pope for the Catholic Church—became a true pope of the Catholic Church when he resigned his leadership role of the Conciliar Church on February 28, 2013. According to sedebenediciplenists, Benedict XVI did public penance for his ecuмenical sins by promulgating Summorum Pontificuм, un-"excommunicating" the SSPX bishops, disciplining LCWR and related groups, and supporting the SSPX; thus, he is no longer a heretic and can be and is a valid pope of the Catholic Church."
