verb: (to give someone the "excellent lizard"): to suddenly discontinue a conversation, especially a phone conversation. Usually for a perfectly good reason, but also, less commonly, because one does not want to continue speaking with the person on the other end of the call.
Origin: OMG, an excellent lizard just ran by. I have to run get my camera. I'll call you back. (True.)
(Out of the blue in a conversation that to this point has been casual and relaxed) "Hey, I'm sorry, but I'm going to have to give you the excellent lizard. A cop just pulled me over."
