Continuing from innately funny words, I also enjoy childish adjectival phrases used instead of the 'correct terms', ie:
Blow-up (for 'inflatable')
See-through (for 'transparent')
Licky sticky (for 'gummed')
It may just be me.
I am recruiting at #TheRoySwallowcliffe and seek waiting/bar staff, an assistant manager, chefs, and a hurdy-gurdy virtuoso. Email t’ manager on [email protected] for more. A golden opportunity to work in the best pub in the world (in Swallowcliffe).
Try the hake.
