Sorry "Scouser" is somebody from liverpool, the running joke is that the stereotypical scouser wears a shell suit (ie. a nylon tracksuit).
So scouser in shell suit on Snowdon is a dream headline.

Geordies are from Newcastle (North east England) the stereotype is that they wear T-shirts or miniskirts in sub-zero weather. A popular joke - how do you tell a Geordie astronaut? He's the one in the t-shirt.
