Mongochops 

A person with no use or purpose. They remind you of something stuck at the bottom of a bin that's covered in bin juice and maggots and no matter how much boiling water and disinfectant you douse it with, it insists on coming back to stink up your fragrant life and bore you to death with their incessant yelping and mewling

Did you hear that Marlene made a total fool of herself last night? The mongochops turned up as a plus 1 to a posh party wearing fancy dress.
