Moment schnell und gell

Moment schnell means please wait a second or a little while. When you are new to a language you pick up what people use often without thinking about it. Moment schnell is something I learned means just wait a little. And I'm soooo good at waiting... Gell means something like 'right?'. Some people use 'oder', meaning 'or', ending the sentence with a question mark. It's like they want confirmation of what they said is correct. Are ze Swiss insecure?
