Someone with a massive head who is also a stupid fucker.
They slide around on their knees as a way of movement.
Have no aim and enjoy wearing helmets.
Probably likes to eat other people's faeces..
'Why is that guy sliding around on his knees with a helmet on?'
'I know right, look at the way he's sliding up to that piece of shit.. Looks like he might eat it.'
'That dude is a serious Gommichan.'
