The cups feature a busy print of holiday favorites like mittens, presents and Christmas trees, and above the logo, two unseen people are holding hands.
Since the cups launched in October, however, people have taken to Twitter with hypotheses that the androgynous hands may belong to a pair of lesbians.
The idea may have sprung up from a video campaign Starbucks launched, advertising the return of the holiday cups. In the video, two women are seen standing at a table holding hands. The campaign claims, "The holidays mean something different for everyone."
