I think you're going to fit in here Masklinn. [img]smile.gif[/img]
Okay, it loses something when it's explained but I'll have a go.
there is a phrase used mainly in London. If someone is being aggressive or loud you might say. 'Oi you! Don't come in here 'giving it all that!''. It is accompanied by a hand movement which involves the thumb closing on the four fingers repeatedly mimicking the acttion of a mouth. (It looks a bit like an ostrich).
The crab of course makes these actions naturally with his claws. So the barman was using both hands to make the 'mouthy' action.
When I told my brother the joke over the phone he laughed. He said he could guess what I was doing.
See?
