Popular theme park in England. Famous for a lot of rides including it's most trademark one, 'Oblivion'. 'Air' is most likely to break down whilst riding it and you're most likely to drop a shoe or hat in 'Nemesis'. A very enjoyable theme park but if you soil yourself on 'Rita' you're screwed.
Also commonly shortened down to 'AT'.
"Let's go to Alton Towers today Mummy, but I mustn't forget to bring a change of pants!"
"AT is so damn cool!"
"Did you hear, that oblivion at AT is so scary!"
