Oi! A word/phrase/guttural noise, spluttered with a splash of indignation, a twist of sarcasm and a great gulp of volume. No matter how hard he tried, the Doctor couldn’t help but sigh every time he heard it. Usually because the indignation, sarcasm and especially the volume were all aimed in his direction. He sighed and turned back to face Donna Noble, Queen of the ‘Oi’s.” - Doctor Who: Beautiful Chaos
