I don't have any specific document or context about "exo showtime2" to refer to, but I can make an educated guess based on the terminology:

"EXO" is a popular South Korean-Chinese boy band formed by SM Entertainment. They debuted in 2012 and have since become one of the best-selling K-pop groups.

"Showtime" often refers to a live performance or concert by the group.

Given this, "exo showtime2" could potentially refer to:

1. A second season or installment of EXO's Showtime reality/documentary series.

2. The second concert or tour by EXO called "Showtime".

3. A special event or performance by EXO that's part of their "Showtime" series.

Without more specific information, it's hard to say exactly what "exo showtime2" refers to. If you're looking for detailed information about this, you might want to check official EXO fan sites, their social media accounts, or music streaming platforms where they officially post updates about their activities.
