A metaphor for slowing down and taking your time (as when you buy a new fish).
Hey dude, don't eat that all at once! Float the bag, man, float the bag.
from the movie "That Thing You Do". An "oneder" is a person who thinks highly of themselves and is frustrated that a certin point is not understood whole in fact, everyone understands it and sees other elemnts far beyond it.
In the movie the douche bag singer thinks writing "wonders" as "oneders"is clever. Everyone gets the pun but also know that radio announcers will pronounce it "oh - nee - ders".
An "oneder" - a person who thinks you do not get their point when you actually do and also see more.
Calling an anti-vaxer stupid is not good way to convince them to get vaccinated. Don't be an oneder.
Similar to Stockholm Syndrome. You get a ride home from a friend but they want to stop for a drink first. Eventually, it turns into a binge instigated by you. You are a victim of the "Helsinki Effect "
Sorry honey, I asked Dave for a ride home after baseball but he forced me to go for a beer. Next thing I knew we were in Tiajua. It was the Helsinki Effect.
