Short for “Duo group-
chat”. A group
chat where there are multiple members, but only two
people actually talk on it and everyone just watches the convos and/or complains about all the notifications.
Deborah: *starts conversation
Nathan: *responds, continues conversation for another 210 messages
Rachel: OMG guys, over 210 notifications in 10 minutes!
Nathan: It’s not my fault that this has become a doup-
chat!
