Zam Clam: is the term used, for when a cheesy joke is inserted at the end of a conversation, and everyone involved laughs. often seen at the end of my 80's sitcoms and cartoons.
The origin of the Zam Clam goes as far back as awkward silences have ended conversations. The actual term begins with Kris Straub and Scott kurtz inventing it in their Daily podcast; "The Daily Affirmation" episode number 11
The band of superheros just finished defeating their arch nemesis, the "BARBER" who is made entirely out of scissors
and as they watch the police haul off their captive, one hero exclaims "Well, that was a "Hair Raising" experience."
Everyone Laughs, role credits.
When used by Kris and Scott, one will make the cheesy joke and they will both laugh followed by nonsensical words i.e. (ha ha bling pow wiz blort Zam Clam. all of this was shortened to the term Zam Clam.
