More from the British movie The Football Factory. The background is that the main character and his best friend have picked up these two girls at a bar; things proceed swimmingly, and the two head over to the girls' house for some hanky-panky. Unfortunately for the guys, both have imbibed a little too much alcohol, and they promptly pass out in drunken stupor, before any intercourse. The two girls seem mutually disappointed; one calls out to the other across rooms,
Shame! He's hung like a pike in 'ere.
And the other replies,
Good for you. I've got stickleback in 'ere.
I'm guessing the meaning here relates to the properties of the two fish, but I don't know anything about them, and don't understand what hung means in this sentence.
