Paris trombone 

1. A type of bike rack used in Paris that allows two bikes to be locked on either side of the rack without the pedals clashing.
2. A variation on the rusty trombone, where both parties are also smoking cigarettes

1. I locked up my cargo bike at the Paris trombone down the street, it's really nice that it accommodates longer bikes!
2. I asked Rodney if she wanted to give me a Paris Trombone but she said she doesn't like the after taste of cigarettes so we settled on a rusty trombone
