A fictitious Englishman, usually played by Colin Firth may use dalliance to charm a lady, but a proper native of Albion shouts this at the object of his desire; usually from a building site or a white van.
Man leaning from scaffolding on building site whistles at pretty lady walking past, and upon gaining her fleeting attention, shouts:
'Oy, darling! Up your guts!'.
