That friend that makes or receives a phone call and then starts having a conversation with someone in the room as well as the person on the phone.
OMG, Lorrie is the worst. The other day she called me and as soon as I said "Hello" she said "Hey" then started a conversation that I could not follow. Then she asked me what I was doing, and then back to the other person then me..... and so on, therefore becoming a Multi Conversationalist. Drives me BONKERS!!!!
