A nowadays excuse
Alty & Levy are standard Mcr school slang. Sounds a bit daft when you're a grown up, but it's authentic enough. Abbreviation suited old-fashioned graffiti that had to be carved into desks & train doors with a compass. 'Manny' sounds odd to me, but the youngsters are all over it currently.Good shout that, bit of a bike ride to Altrincham though.
Heard quite a few people calling Altrincham and Levenshulme, "Alty" and "Levy." Sounds wanky as fuck.
