To believe anything you are told when it comes to chatting up a member of the opposite sex. 'Plapperts' are stupid, oblivious and will do whatever you tell them to. They think they are talking dirty but really they're just talking a load of funny shit and it gives everyone around them a good laugh.
'I dream of shaving you head, eyebrows included, so i can redraw some features with a permanent marker to make you the perfect woman. this is often the dream i have before i wake up in my own piss.'

'Do you want me to talk dirty? Yes or no.'
'Yes.'
'Okay. I want you to make me purr with excitement, for Roberta, for Peter and for Phyllis, for i am the embodiment of the railway children and subsequently i do like a good rag on.'

'He's such a Plappert!'
