The act of inserting yourself into conversation, many times dropping whatever you are doing in the moment just to be present in other's conversations. Other variations include eavesdropping noticeably, listening in on phone calls while muting yourself, and randomly just sitting in other's private spaces saying nothing.
Dude, don't you have something better to do? Stop Dunning! You don't have to be part of every conversation
