To 'meep' is to talk and talk and talk without really adding anything to the conversation. If you meep, you don't really have anything interesting to say, you're just speaking because you can.
If you meep, you become, a meeper.
The words 'meep' and 'meeping' and 'meeper' were created by Benjamin off Big Brother Australia 2012.
