mock talk 

the sound that one hears when one is in a room and hears multiple conversations occurring, yet the person cannot understand what any one person is saying.

Jimmy could not hear Susie talking because the mock talk was too loud at the banquet.

mock talk 

When you talk about something that literally no one has any clue, or create an inside joke that only a select few find funny while everyone else finds completely ridiculous.

Seth: OMG sup y'all
Olivia: Heyyyyyyy ;)
Seth: When J.E doesn't anything about the closing arguments HAHA
Olivia: Omg ikr!
Hanny: Omg wtf stop the mock talk...
