Comms is short for communication but has been associated with another meaning lately: when people on social media use it, they generally mean the issuing of secret signals to those who are interested in the messages of Q, the so-called Anons .
These comms will for instance be hidden in news event like the seizing and euthanizing of Peanut the squirrel that is in the news this weekend, but which might also point to the only president who was called apparently a peanut farmer, Jimmy Carter.
