kazoo
to kazoo is to attempt to have exactly the same conversation with multiple people, often simultaneously.  this can easily be done using cut and paste in an instant messenger program, but can also be done verbally. although the conversations are initiated identically, they have the potential to vary tremendously and follow completely different directions.
Scott: look what Chris just said: "i am an angiosperm"
Brendan: omg, he said exactly the same thing to me!
Scott: we have been kazooed!
