Apparently, they're the TEEN TOP members' 'prison' names?

Fans got a little glimpse of the boys in the orange prisoner jumpsuits in their first teaser, and now the first photo teaser of the boys shows that not only are they in prison outfits, they've also got new nicknames(?) for themselves!

C.A.P is apparently called MUSTANG82, Niel became FULLLIPS12 (rather fitting for Niel don't you think?), L.Joe became GANGJOE11, Chunji - SCATTY77, Changjo - WANNABESUN99, and Ricky - OOMPH27.

We don't know yet if these names actually mean something for their comeback, or if they're just meant for our amusement, so stay tuned for more news on their comeback!
